How a differential works proof video

Hey guys, I made this video for fun using my simulation program. It's about how a steering differential works. I was inspired by (and stole audio from) a great 1930s science video. Let me know what you think and forgive the one or two editing errors; my 200 dollar editing software loves to corrupt the project when it is 99% complete and sacrifices have to be made.
