Simple HTML5 Interactive ball simulation

This is an HTLM5/Javascript/CSS simulation I made that starts simply from bouncing balls. You can change the arena, add balls, remove balls, and I am rapidly updating it (it doesn't take that long to add a new feature)

each ball is random except for the starting balls. I plan to add specific ball editing, but it isn't here yet.

The buttons for interaction are at the top of the simulation. Not very styled, but like I said, early version.

I do plan to upload the source code, just haven't gotten to that yet.

Enjoy!
