If you haven't read a Phillip K Dick novel, do yourself a favor and pick one up at the library. This guy's stories are the basis for countless movies. The next one in line looks to be Scanner Darkly [QuickTime trailer]. It looks pretty darn cool, check out the cool motion capture to animation technique.
UPDATE: Thanks to the guys at Boing Boing for posting this by Rustmonkey, earlier concept for Scanner Darkly. I like it better.
