These are real urinals and they are available for sale. Clark Sorenson is a San Francisco-based artist and you can buy one of these flower urinals through his website. Astounding. Even more so when you stop and think about what a flower is when you get right down to it. All I can say is wow.
Many thanks to the lovely and talented Melody McFarland for the great find. Check out her blog, I Like Pigeons Because Nobody Else Does.
