Well I've just balanced a whole lot of dominoes up and what I wanted to do is look at how computers actually do maths for us. How on earth can a mechanical system like just a chip in a computer - how can it actually do arithmetic. This is my input Domino here. If I bump the input Domino it's going to send a signal down the chain and normally you just have a one single chain of dominoes so I've mixed it up by... well initially splitting the chain which in itself is not that controversial but then the shorter arm over here knocks out some of these dominoes so if these dominoes come toppling over it'll bump these two out and this won't be able to cross. So in fact this is a circuit that stops itself. If I bump this and it starts goin...
