============================================================================

Things I want to add / improve for V.002:

1) make the circle a triangle
2) switch from repaint(); to buffer strategy
3) move rectangle to the center of the window
4) make the oval dependent on window size
5) make it so that the oval doesn't go through the rectangle
6) make the oval drop automatically
7) add more obstacles
