I chose to do a bowling ball and a ping pong ball.
We were also encouraged to go out and find video reference for our animation and our substitute mentor this week Paul Allen sent us a bunch of really great video files. This is one that I used quite heavily as reference for mine.
My ping pong ball unfortunately turned out looking more like a super bouncy ball, but oh well.
I haven't had a chance to go back and revise it yet, but I may get rid of the crazy back-spin on the ping pong ball because I'm not sure of how well it's reading.
