That depends on what version of Windows you're running :). It's at least a lot more fun to watch it work, but the reliability isn't all that hot - I think I remember that a reasonable multiplication ends up taking a couple of hundred gate interactions, so if the reliability of the gate design is 99%... you'd still never get an accurate calculation. Getting the reliability of the flip-flops up above 99.5% for a single gate was a serious issue.

Getting it to do that would be one thing. Getting it to do that on the kinetic power of those light soccer balls would be the tough part. Might have to go to something a bit heavier.
