when i came down to the computer room, my sister was watching a youtube video that was shot, seemingly, in the dark. i asked her what she was watching, curious, because she IS an 8 year old after all, and she should be watching... um, Blue's Clues... no, um, a show that was shot in good lighting at least. It turns out that she was watching an artist who draws in his sleep.
Some of his works, all done while he was asleep:
check out his gallery. his bio. Like, a sleepdrawer? sleeppainter? whatever he is, he is amazing.
