I'm about to head out to teach a class introducing animation for videogames at the Yarborough Branch Library here in Austin! If you're reading this and you came over from there, howdy and I hope it was interesting :)
If you'd like to learn more, follow this link to a Google doc I put together for additional reading! While it's written of the perspective of a sprite-animator (especially the links), most of the info is general enough to apply to almost any technique you choose to work in.
Keep learning, and have fun!
