I found this video several months ago and showed everyone at work; we were all pretty fascinated. I personally find this stuff brilliant; at least someone got paid to do this. :-P
Before people start asking questions, "Pitagora Suicchi", the phrase they keep singing in that annoying little jingle, is katakana for "Pythagorean Switch", basically how they say a "Rube Goldberg" device.
Good stuff, and everyone should be familiar with Goldberg and his counterparts (this type of machine is named after different people all over the world :-P).
I actually see these on TV every once in awhile.
