Thanks for the suggestion slower, but part of the fun to me is that I am doing this all from scratch, save for a bit of code borrowed from nccb to rotate the edges of the blocks.

Yes Jrlowe, there are some bugs with boxes where the corners hit. I am not too worried about it though, since boxes can't intersect in real life. I might do something to stop the boxes from hitting like that though.

Also, I suggest creating an offset according to the angle the box hits the ground. For example, if the box is at a 45 degrees angle, it should be slightly above the ground than if it hits the ground at a 90 degrees angle.
