The OS isn't getting faster. You're slowing down with old age. That just makes it seem faster.

Never used UPS for shipping anything have you?

Pretty much, except we actually had a normal water gun instead of just the pump, and were using a Z8 board....

Start with a battery powered watergun. Add a couple of small motors to pan back and forth, and to adjust angle up and down. Next, you'll need a ultrasonic rangefinder. Hook that all together, and write a piece of software for a control computer to watch for differences in the distance that it thinks things are at. Scan back and forth, and look for things that are different, then hose them down. We almost got to build one of these, until we mentioned to the prof that we wanted to fill it with naptha, and add a sparker in front of the nozzle of the squirt gun...

Sigh. And i had such hopes. Pictures of a team of people, with a spam and tennis ball loaded tennis ball launcher at the other end of a court. When something gets fired at you, determine if you should let the ball go by, or wack the spam from the air. Alas, it's not to be. Dan
