This is a 10-minute timelapse (plus some individual closeups of certain sections) of a 1-million pixel collaborative digital painting constructed by users of subReddit /place. Over the course of 72 hours all users were allowed to alter the pixels, but only one pixel per user per five minutes. I watched the whole thing live, and I've got to admit, I've never been glued to the edge of my seat so hard for 72 hours. I mean, besides those other 72 hours. "You mean the 72 hours you were actually glued to a toilet seat." The doctor was afraid I was going to lose my balls.
Keep going for the video.
Thanks to Kika, who agrees the best art projects are the ones undertaken with friends, like those painting-and-wine-nights where everybody paints their own crappy sunrise.
