Eurodemo parties feature competitions not only for demos but for art, music and now flash and video as well. In the video or animation category check out Tension. Some nice imagery and music.
Speaking of imagery if you haven't see it check out Lots Of Robots. Click the LORtheMovie link. Rocketpants is also well done but disturbing. Shows what one guy can do with 3D software, some talent and alot of time.
