some online animation

http://www.blender.org/features-gallery/movies/

in particular you want to look at Big Buck Bunny (8min) and Murnau the Vampire (27 min). BBB was an easy download. Murnau was not; apparently there are torrents, but that seems to not work for me any more...despite a brand-new BT. Which is too bad, this is an exceptional bit of animation; not available in hi-def, tho.

fwiw, F W Murnau was the director of Nosferatu, the first, silent, vampire movie. Apparently you can see it online HERE.
