Name of this sweet browser game.?

Ok so its this game were you have a red ball and you need to move the red ball to this spot by building a contraption using like 10 or 12 parts that have there own mechanics. you can build anything as long as the ball will move to designated spot. I know there are these wheels one is like orange I think and it moves one way and there is a blue wheel that moves another way. And there is this blue wire stuff that can connect anything together. I do believe that the last name of the game is contraption. Thanks
