Physics Sandbox With Boxes and Balls

It's a physics sandbox with boxes and balls - if you didn't get that already.

Controls:

- left click to create a ball

- right click and drag to create a box 

- you can drag the balls and boxes around by holding left or right click on them

- middle click while dragging stuff to delete it

- there are a bunch of cool toggles and stuff in the settings to change how the simulation works

That's pretty much it!
