Here are a couple Gaming & Film /CG related sites that I've found useful at times:

Codemasters, an awesome company where I currently work as a Senior Producer.

Autodesk producers of content creation tools for both film and gaming.

gi - GameIndustry.biz - A great UK site for everything news / business related in the gaming industry, gi is a great place to get info fast.

The 123'rd - A resourceful 3D Art site with daily newsletter, nice content and much more.

HighEnd 3D is an interesting site with everything from news to forums for posted work...both good...and less than good...

The University of Southern California's Computer Graphics and Immersive Technologies Laboratory is always a fun stop. With current projects from creating photorealistic human faces, expression cloning, practical human hair simulation, immersive panoramic video, augmented reality / motion tracking, and much more...its awesome BRAIN CANDY for the Intellectually-challenged. Check it out. Plus it's my alma-motter so it's gotta be cool. ;-)
