Spider Man

Just when I was thinking the human race was getting too stupid to invent anything interesting - this contraption showed up this morning:

It arrived sitting on a flat-bed truck all folded up. It spread out its legs, lowered them to the ground then lifted itself so the truck could drive away. Then it lowered itself to the ground, folded up, and ran on the rubber tank treads into my back driveway so it could work on a neighbor's tree. The trimmer guy hooked himself up in the basket and lifted 60 feet into the air to do his work. They made quite a mess in my driveway, but they are cleaning it all up now.

Fascinating! I want them to leave it behind, so I can hook up a few microcomputers and teach it how to walk all by itself. Should not be too hard to do! It would have made a great lab project for my students back when I had those around. Hmmm...
