A contest by the Hirshhorn Museum and Sculpture Garden, where the artists were limited to using a single sheet of paper, has sparked some impressive results. Not quite pixel art, but certainly minimalist.
Wow, that was awesome. I adored the ones with the tree, man hanging and the skeleton, great concepts. And then the one with the massive towering house thing (was it massive? i couldnt tell). Awesome find iST, thanks! And wow i just looked at the others, the boat one in the stream was awesome, and then the big castle was neat. At any rate this is my favourite, i love how they cut out the chair to look like a shadow. Lovin the whole page, seen the sidewalk things before but then the hand ones are sweeet.
