There's a wonderful "Happy 4th of July and Happy Birthday Rube Goldberg!" animated logo on Google today, which captures both the spirit and the relentless logic of a Rube Goldberg machine. If you either click on the logo or search too quickly, you'll miss the animation. You need to wait about 4 or 5 seconds for the action to start.
To quote from Wikipedia about what a Rube Goldberg machine is
A Rube Goldberg machine is a deliberately over-engineered machine that performs a very simple task in a very complex fashion, usually including a chain reaction. The expression is named after American cartoonist and inventor Rube Goldberg.
Happy 4th! Happy birthday Rube Goldberg!
