Also on Topless Robot, I got directed to this bit of brilliance.
A half-hour long animated rendition of HP Lovecraft's "In the Mountains of Madness," by an Italian group calling themselves Cthulhu Films. You'll need to turn on subtitles, but it is so worth it.
It's a heady blend of 2- and 3-d animation, beautifully atmospheric, with some seriously cool rendered scenery. The 2d stuff is a bit primitive, but effective. I really enjoyed it.
