Marble binary calculator

Cool. I like it. Actually pretty good for demonstrations. In the comments . . . Why do people say they have a completely useless device? Its not at all . . . .
 
Man, I just showed my wife (not techinically minded at all) that device and asked her if she understood how it works, and she said "yeah, but that's simple" and I then told her that a lot of people don't think binary is simple, and she was like "what do you mean" and then I told her that if she understand that then she knows all there is to know about binary....

I gotta say i'm well impressed.
 
hes got a cool way to add, now if only he could find a way to subtract, or possibly multiply/divide, then that would be realy cool, although proberly a LOT more complexity would be needed for multiply/divide, but subtraction wouldnt be too hard.
