What is the name of this old computer game?

I used to play this game about 8 years ago. It was for computers, and the point of it was to make inventions that would transport something across the screen or turn on a switch. For instance, you could make a bowling ball fall on a teeter-totter, which had a tennis ball on it that hit a bucket of water that turned on a fan, etc. The name "something Contraption" or "something Invention" comes to mind... Sorry I don't have any more details! Any ideas?
