Algodoo

Once the scene begins, the first red block drops due to gravity causing the wedge leaving the wood ball in place to dislodge and fall to the orange block where it hots a cement block. The block falls and hits the ball below causing it to roll away. I had a difficult time changing the size of some of the shapes, but I got it to move. Gravitational movement was simple, and I was able to create some movement for my scene.
