This is M.C. Escher's Waterfall. For the less-informed, if you look closely at this picture, you'll see that the water flow is an impossibility, though on two-dimensional paper, it seems like it ought to work. Notice how even the supporting columns look right at the top, but not at the bottom.
Well, thanks to RocketBoom, I found this clever contest held on Worth1000.com. The rules are thus:
I thought this was clever. What would a child Escher have handed in to his art teacher? And what would his teacher's responses likely be? Here's an idea:
We've all got to start somewhere, even the art masters. In this contest your task is to depict the masterpieces of the renassiance [sic] masters (or other time periods) as they were drawn when the masters were children. Do not simply edit existing masterpieces - recreate them through a child's eyes (i.e. a 3d cube would be an early MC Escher, or a paint by numbers Mondrian).
The rules of the game are thus: Show the works of the art masters (sculptures, sketches, and paintings are all fine) as though they were created by the masters when they were children (as in the themepost, "Baby Warhol" by meowza). As always, quality is a must. We will remove poor entries no matter how much we like you. You'll have 48 hours for this contest, so make your submission count.
