Drag the balls around too adjust the triangle. It is a "little bit" glitchy, so sorry for the inconvenience.
BUGS: 1. If you move the mouse too fast, then the ball will not follow the mouse pointer, so move the mouse slowly. 2. If you drag a ball too close to another ball, the other ball AND the current ball will follow the mouse pointer, so don't move a ball too close to another ball.
