Who else here loves Rube Goldberg devices? If you don't know what they are look here.
In general, a Rube Goldberg machine is an overly complicated device created to do a simple task. They were invented by Rube Goldberg, whom stated "when people are given the easy way and the hard way to do something, they always want to do the hard way."
Examples include the trap from MouseTrap, a car commerical that is titled "Cog", and some of the things done in Garry's Mod. Just search the internet for a few minutes, and you'll find some of the most amazing Rube Goldberg machines. I'm telling you, those videos will amuse you, no matter how mature you think you are.
By the way, this is Cog.
