Cranks, gears, and levers are just the beginning of the machine components you can use to build Rube Goldberg machines in this crazy piece of software. Beyond the basics you have such silly components as robots, cannons, blimps, plants, balls, and much more.

Each level has a task to complete, and a specific set of components required to complete the task. The user interface is very simple, and whether or not you solve the puzzle on your first try, you'll have great fun watching your machine in action.

The software is built on a real-physics engine, which simulates gravity, air pressure, and electricity.
