The game that is Gravity

i came across this game on the internet- flash based, however, terribly addictive. I am not trying to score top points, but jus trying to complete each level.

you have to move the ball to pick up all the magic balls on the way. you need to draw shapes with the mouse to move the ball- all using the laws of physics. So, use levers, weights, inclines etc and move it...
try it- its addictive!
