I has a notion to do some animation for an collaborative effort with by son to create a video. The animations will be fairly simple set in front of a relatively more detailed background. It'll basically be bunnies and similar critters chatting or moving about a little. There will, of course, be audio.
So, having said that, can anyone recommend a inexpensive or free program that would work? Bear in mind that I have zero animation experience outside of helping the (ex)wife make an animation for a web page in the '90s.
