A spidery dilemma

I have a patio. It's on that patio where I grow my orchids and other plants. It's covered and one of my favorite things in the world is to stand out there while a thunderstorm rolls in. I have a dining table out there and my second favorite thing in the world to do is to have people over for dinner al fresco --my Christmas Eve dinners are legendary. I spend a lot of time on that patio and I do what I can to encourage geckos to hang out, they keep the mosquitoes at bay. Similarly, insects like paper wasps eat the caterpillars that crop up on my ferns and spiders keep the rest of the undesirables in check.

I don't have any prejudices against pesticides and I'll use them if the situation warrants it, but I prefer to have something resembling a functioning eco-system out there. Watching the cycles of life and death play out, and observing the dynamics of predator and prey is fascinating. I like to imagine myself to be a passive observer and so I tend to let the system out there regulate itself.

Well all of that changed on Sunday. I was watering my plants and I noticed something in the base of the pot I have a tangerine growing in. By base, I mean the drainage hole. The pot has side drainage (that allows the roots to air out between waterings --citrus trees love to have aired out roots). Anyhow, here's the the drainage hole.


I don't have a decent lens so the rest of the photos I'll use here are ones I found around the internet.

What I saw lurking around was this spider.

As a rule, spiders don't freak me out in the least. They are absolutely fascinating creatures and despite the fact that they are everywhere, how much we know about them doesn't amount to much. Most of them aren't too tough to identify but beyond that, nobody seems to know a whole lot about them.

The spider I saw was pretty small, about an eighth of an inch long, but I've been around enough to know what it was. I suspected from its body shape that it was a juvenile black widow and sure enough, I got a positive ID from The Bug Guide. The Bug Guide and its companion website What's That Bug? Are fantastic resources for IDing these sorts of things.

It's too small to be able to tell if it's a male or a female but based on my location , it's a safe bet to call it  Latrodectus mactans, the Southern Widow Spider. L. mactans ranges as far north as New York State by the way, and there are members of the genus Latrodectus found all over the world.

Here's a photo of a mature Latrodectus mactans. Note that the hourglass shape is on its underside, not on its back as is commonly believed.

That marking by the way, varies greatly from spider to spider and many of them do have red markings on their dorsal sides. Here's another photo of a mature female.

Florida's also home (as are a lot of other places around the world) to another widow spider, Latrodectus geometricus. No one seems to know where L. geometricus originated but its range is spreading rapidly.

Anyhow, widow spiders have a job to do and they're particularly good at it. While it's true that they can bite and that bite is not very pleasant, they aren't an aggressive species. Few spiders are. The only way that the L. mactans on my patio will ever bite me is if I pick it up once its an adult. Even if it did bite me, I have an intact immune system and no underlying health problems. Though it would hurt like crazy and not look real pretty as it healed, it wouldn't kill me.

When it's mature, it'll be nearly an inch long. That's big enough to take down a palmetto bug and that's makes L. mactans OK in my book.

At the same time though, it could also do a number on me. Though I'd never pick up an L. mactans, I could grab it accidentally while I'm puttering around out there some day.

So what to do? Do I mete out the terrible, swift justice of a can of Raid or do I let it go about its life in the base of my tangerine? On one hand, it's a beautiful creature. It's perfectly evolved for the life it leads. On the other hand, it's my patio and my interests trump the spider's.

What would you do?

A custom mosaic of my very own, courtesy of Trend USA

Trend USA, an Italian mosaic producer with offices around the world, announced a new process for making mosaics recently. It's something they're calling an elaboration, and to achieve it they use proprietary CAD-based software to assign colors and patterns to replicate in mosaic form photos, fabrics or other works of art.

Sometimes it's easier to show than to explain. So here's an image of a fabric.


And here's its elaboration as a Trend USA mosaic.


It's been assigned a different color way of course, but notice too that it's made with cut mosaic pieces. That's an ancient process for achieving rounded shapes called tessellatum tesserae. The same proces is sometimes called a cut mosaic. In addition to tessellatum tesserae, Trend USA's new process can be used to create mosaics using whole 3/8", 5/8" and 3/4" mosaic tiles as well.

In the example below, there's a photo in the top right corner. Below it are the full image of the photo as a mosaic created in 5/8" tiles and then there's a detail of the mosaic. I'm uploading these photos today in high resolution. Click on them and you'll see the detail. It's a small price to pay for the slower loading times.


Trend USA asked me to submit a photograph of my own to use as an example of this process. Trend USA is represented by a friend of mine and she's well aware of my near obsession with Fibonacci Sequences and she suggested that I submit an artistic example of one to use for my custom mosaic.

My favorite video of the last year is Nature by Numbers, a short film by Cristóbal Vila that uses three examples of natural geometry.





I have a still from Vila's film and so I sent this image to Samara Gould, Trend's Artistic Design Consultant. I wanted to test this new process, so I picked an image specifically because I thought it would be a challenge. The transparent wings alone would make me sweat if I were Samara. She accepted my image without hesitation. In fact, she was excited to give it a go.


I told her that I would love to see that dragonfly elaborated as a mosaic in a size somewhere around 10 feet wide by five feet tall.

Samara used 3/8" tiles and by using that smaller size, she created a mosaic that would be readable from four feet away. That's pretty good for something this large.



If I were to buy this dragonfly mosaic, it would come to me in sheets 28 tiles wide by 28 tiles tall and all my installer would have to do is take the sheets out of a box and attach them to my wall. That's pretty slick.

In addition to Trend USA's new custom program, they have pioneered the use of recycled glass in glass tile and their products have recycled content percentages that range from 55% to 78%. You can read more about the company and their commitment to sustainable practices on their website here.

I've seen many custom mosaic services that use a computer to assign colors and patterns before, but I've never seen one that results in this level of detail and clarity. A process such as this is yet another reason to keep an eye on Trend USA and Trend Worldwide. Thank you Samara and thank you Trend.

It's a urinal! It's a sink! It's both!

Lloyd Alter is the lead irritant of the usually irritating website Treehugger. On Friday, he posted something on that site that stood head and shoulders above anything I'd ever seen him write about before.  And here's what he wrote about.



It's a sink and urinal combination. After a gentleman finishes his business, he washes his hands in the sink in front of him and the water from the sink drains into the urinal and flushes it. It's absolutely brilliant.

This sink/ urinal was designed by Yeongwoo Kim, a young designer from South Korea. He won an International Forum Design, Design Concept Award this year for his efforts and he had this to say about his creation:
To save water, Eco Urinal is designed to use the water that was used for washing hands to flush the urine. By this process, we don't have to use water twice after using the urinal.

Moreover, it reduces the establishment expenses by optimizing the materials. Upper space of this urinal is made with glass, and it helps to secure a clear view for users. It also promotes people to keep their sanitation because people need to wash their hands to flush the urine after use.
It's the ultimate gray water solution and it'll make plumbing something like this half as complicated and half as expensive. I think it's brilliant.

In looking over the comments though, people really flipped out. From the tone of of a lot of them, you'd think they were being asked to bathe in pee or something.

What do you guys think? Good idea or bad idea? Am I too much a libertine (hah!) to have a problem with this? What do The People think about this?

Martin Luther King, Jr. had a dream 47 years ago today


I am happy to join with you today in what will go down in history as the greatest demonstration for freedom in the history of our nation.

Five score years ago, a great American, in whose symbolic shadow we stand today, signed the Emancipation Proclamation. This momentous decree came as a great beacon light of hope to millions of Negro slaves, who had been seared in the flames of withering injustice. It came as a joyous daybreak to end the long night of their captivity.

But one hundred years later, the Negro still is not free. One hundred years later, the life of the Negro is still sadly crippled by the manacles of segregation and the chains of discrimination. One hundred years later, the Negro lives on a lonely island of poverty in the midst of a vast ocean of material prosperity. One hundred years later, the Negro is still languished in the corners of American society and finds himself an exile in his own land. And so we've come here today to dramatize a shameful condition.

In a sense we have come to our nation's capital to cash a check. When the architects of our republic wrote the magnificent words of the Constitution and the Declaration of Independence, they were signing a promissory note to which every American was to fall heir. This note was a promise that all men, yes, black men as well as white men, would be guaranteed the unalienable rights of life, liberty, and the pursuit of happiness. It is obvious today that America has defaulted on this promissory note, insofar as her citizens of color are concerned. Instead of honoring this sacred obligation, America has given the Negro people a bad check, a check which has come back marked "insufficient funds."

But we refuse to believe that the bank of justice is bankrupt. We refuse to believe that there are insufficient funds in the great vaults of opportunity of this nation. And so we have come to cash this check, a check that will give us upon demand the riches of freedom and the security of justice.

We have also come to this hallowed spot to remind America of the fierce urgency of Now. This is no time to engage in the luxury of cooling off or to take the tranquilizing drug of gradualism. Now is the time to make real the promises of democracy. Now is the time to rise from the dark and desolate valley of segregation to the sunlit path of racial justice. Now is the time to lift our nation from the quicksands of racial injustice to the solid rock of brotherhood. Now is the time to make justice a reality for all of God's children.

It would be fatal for the nation to overlook the urgency of the moment. This sweltering summer of the Negro's legitimate discontent will not pass until there is an invigorating autumn of freedom and equality. Nineteen sixty-three is not an end but a beginning. Those who hope that the Negro needed to blow off steam and will now be content will have a rude awakening if  the nation returns to business as usual. There will be neither rest nor tranquility in America until the Negro is granted his citizenship rights. The whirlwinds of revolt will continue to shake the foundations of our nation until the bright day of justice emerges.

But there is something that I must say to my people who stand on the warm threshold which leads into the palace of justice. In the process of gaining our rightful place we must not be guilty of wrongful deeds. Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred. We must ever conduct our struggle on the high plane of dignity and discipline. We must not allow our creative protest to degenerate into physical violence. Again and again we must rise to the majestic heights of meeting physical force with soul force.

The marvelous new militancy which has engulfed the Negro community must not lead us to a distrust of all white people, for many of our white brothers, as evidenced by their presence here today, have come to realize that their destiny is tied up with our destiny. And they have come to realize that their freedom is inextricably bound to our freedom. We cannot walk alone.

And as we walk, we must make the pledge that we shall always march ahead. We cannot turn back. There are those who are asking the devotees of civil rights, "When will you be satisfied?" We can never be satisfied as long as the Negro is the victim of the unspeakable horrors of police brutality. We can never be satisfied as long as our bodies, heavy with the fatigue of travel, cannot gain lodging in the motels of the highways and the hotels of the cities. We cannot be satisfied as long as a Negro in Mississippi cannot vote and a Negro in New York believes he has nothing for which to vote. No, no, we are not satisfied and we will not be satisfied until justice rolls down like waters and righteousness like a mighty stream.

I am not unmindful that some of you have come here out of great trials and tribulations. Some of you have come fresh from narrow jail cells. Some of you have come from areas where your quest for freedom left you battered by the storms of persecutions and staggered by the winds of police brutality. You have been the veterans of creative suffering. Continue to work with the faith that unearned suffering is redemptive. Go back to Mississippi, go back to Alabama, go back to South Carolina, go back to Georgia, go back to Louisiana, go back to the slums and ghettos of our northern cities, knowing that somehow this situation can and will be changed. Let us not wallow in the valley of despair, I say to you today, my friends. And so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream.

I have a dream that one day this nation will rise up and live out the true meaning of its creed: We hold these truths to be self-evident that all men are created equal.

I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave owners will be able to sit down together at the table of brotherhood.

I have a dream that one day even the state of Mississippi, a state sweltering with the heat of injustice, sweltering with the heat of oppression, will be transformed into an oasis of freedom and justice.

I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character. I have a dream today!

I have a dream that one day, down in Alabama, with its vicious racists, with its governor having his lips dripping with the words of interposition and nullification; one day right down in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers. I have a dream today!

I have a dream that one day every valley shall be exalted, and every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed and all flesh shall see it together.

This is our hope. This is the faith that I will go back to the South with. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of brotherhood. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day. And this will be the day, this will be the day when all of God's children will be able to sing with new meaning, "My country 'tis of thee, sweet land of liberty, of thee I sing. Land where my fathers died, land of the Pilgrim's pride, from every mountainside, let freedom ring!" And if America is to be a great nation, this must become true.

And so let freedom ring -- from the prodigious hilltops of New Hampshire.

Let freedom ring -- from the mighty mountains of New York.

Let freedom ring -- from the heightening Alleghenies of Pennsylvania.

Let freedom ring -- from the snow-capped Rockies of Colorado.

Let freedom ring -- from the curvaceous slopes of California.

But not only that.

Let freedom ring -- from Stone Mountain of Georgia.

Let freedom ring -- from Lookout Mountain of Tennessee.

Let freedom ring -- from every hill and molehill of Mississippi, from every mountainside, let freedom ring!

And when this happens, when we allow freedom to ring, when we let it ring from every village and every hamlet, from every state and every city, we will be able to speed up that day when all of God's children, black men and white men, Jews and Gentiles, Protestants and Catholics, will be able to join hands and sing in the words of the old Negro spiritual,

"Free at last, free at last.

Thank God Almighty, we are free at last."

--Dr. King delivered this speech on 28 August 1963, at the Lincoln Memorial, Washington D.C. Never forget what he said, when he said it and why he said it.
