Hey guys!
I made a really sweet bouncy ball simulator program, and you can download it here.

I had a lot of help from JWinslow23, who slimmed down the program nearly 12.5% (Which doesn't seem like much, but it was quite a bit of clever programming.)
You can add velocity to the bouncy ball with the arrow keys, and quit with [del]. Enjoy!
