The delightful Kelly James from Design Ties is recuperating from knee surgery this weekend. She loved the illusions from Richard Wiseman I ran the other day and asked for more. Kelly's favorite color is purple and she needs some distraction right now, so these are for Kelly specifically. However, anybody can join in on the vertigo-inducing fun.
First up, a "moving" static image.
Stare at this for a sec and then try to get it to stop moving.
Second up is another twist on fooling your brain.
The warped lines in this illustration are pretty plain to see. Or are they? Hold a straight edge up to your monitor and you'll see that there's not a bend to be had. Pretty cool!
Thanks again to the great and powerful Richard Wiseman and good wishes to Kelly.
