The emphasis here is on free tutorials which are either hosted here on cgspeed.com because they meet the goals of this site, or tutorials hosted elsewhere which I've found useful as an animation hobbyist.

Tutorials local to CGspeed.com:

-- Real-time Camera Motion Recording in Maya for under $50: Using a SpaceNavigator for Maya Camera Flythroughs
-- Installing Maya 8 on Fedora Core 8 Linux
