I came across this video, which has been making the rounds on the ole intartubes as of late. A student artist made a 5 minute animated movie. Impressive, right? Not really. Until you consider that each frame, instead of being a rendered cell, is a fully developed painting. It took 2 years to paint the 6,000 individual paintings used to make the clip. And the music is pretty cool too, if you're into that kind of thing, which I am.
