OT: Animation Software recommendations

[slidey]

I've done some work on iMovie before, fairly trivial but now I want to make a video with a specific purpose in mind - to explain a concept.

I'm thinking of videos along the lines of this (http://youtu.be/rj3n4O6tstM) or this (http://youtu.be/6vZ0iqUS6sg).

It'd seem that stop-motion animation is the quickest way, so does anyone have free, and easy-to-use software for doing so on the Mac? In the off-chance that stop-motion animation isn't the way to go, any pointers are welcome.

I do, I'll remember it today at some point or when I get back to my Mac tomorrow..

Not free, but the software from "Stop Motion" is great and easy to use.
