I did some claymation back in Middle school and High School. It's not great but it's something.

I'd recommend getting some software like iStopMotion for Mac or Stop Motion Pro for PC as well as a video camera. Claymation is actually fairly easy as long as you have some patience. You can make the figures using wire frame "skeletons". The last video shows what a "skeleton" looks like. Finish your voice track first and then sync your animation, one frame at a time, to that. We used studio lights but any old desk lamp would probably be fine for lighting, just don't let it get to hot or the clay will get soft.
