* Description: An asteroids inspired interactive drawing where the 
vertical mouse position controls the placement and alpha of the 
asteroids and the horizontal mouse position controls where the ship
is. Also, the stars are paralaxed towards the mouse and the screen 
flases when the mouse is clicked.
