What is the flash physics game where you can place clockwise/anti clcokwise wheels and stick and water rods?

The question says it all really.
I stumbledupon this Flash game but forgot to favourite it. I can describe it:
You have to get a pink box/circle to a certain zone, overcoming obstacles and you can place a water rod, a stick rod, and various wheels. You can also save your designs.

Anybody know what this game is called, it’s not in my browsing history.
