Day 3

I am still struggling with getting the trajectory of the balls right. Simple math, but somehow I fail to get it working just right. However, we do have collision detection so the balls bounce off the walls (and off the blocks soon too I hope).

I was really hoping to get this done, however, since this is more or less the main game dynamics spending some time on it seems justified. But that also means I still have no pretty pictures to show. Hope to add background and sprites very soon.
