I have always been fasinated with the idea of making a machine that could produce a compleatly random sound or movment. This is a  doomed mission, the reason being that as time and space are infinate, at some point, in some place, all the nessasary components will come together to produce me typing this mail again.
So at some point, my random machine won't be very random any more.
Well, in the words of Jennefer Aniston, that's enought of the science.

My drawing for the gear wheels. The next drawing was made straight onto the wood.
