Any day we create that much shrapnel is a good day.

There are a lot of times when we can just time something and say "busted" or "confirmed" or whatever, instead of building a robot or some gadget to make it happen more elaborately. In those cases, we're simply enjoying ourselves.

One of the things I'm likely to start building in my shop is a vehicle wherein each wheel has basically a flight-simulator base as its suspension. It's known as a hexapod; it's basically a tripod but each leg is two pistons. So you have six axes of freedom on it.
