Algodoo

So I was just breaking physics with spring boxes and so I found out that I could change the spring constant to infinity. I did it. Twice. And then I checked it only to find out that spring constant no longer existed. So I made the spring opacity 0, changed the cube colors, and applied tracers to basically make a group of seemingly normal cubes with the ability to gain energy from other cubes and change terminal velocity. They are also abnormally shaky.
