Speaking of obsessive-compulsives, this hand-made Modest Mouse video by Max Tyrie is simply stupefying:

Myself and a couple have friends have entered the above into the Modest Mouse video competition. Using green screen footage provided by the band we cut a simple music video. We then degraded the images and printed out each frame sequentially. (all 4133 of them) We then nailed each "shot" of 50-100 posters to various structures and posts. Then using a digital SLR camera with a long exposure we frame by frame shot each poster. Oh, and theres a little video projection (again, frame by frame on the SLR) just to mix it up. There is no compositing, no shortcuts, just lots of blood, sweat and tears, and a huge Kinkos bill!
