Well, I guess you had to be there. It's a very simple machine made of a camera tripod, a battery-powered "Shiatsu massager", and some assorted odds and ends.

The bottom of the motorized massager unit goes around and around, and to that I attached some bent bicycle spokes that hold little finger-and-thumb like clamps that in turn hold either a marker pen or (as pictured) an "automatic tongue" (envelope flap moistener) filled with an alcohol and water solution. This turns around and around on top of a small drawing on a card - I made a few different ones but mostly they are rubbings of block prints I've made, using a combination of graphite and water-soluble pencil and crayon. The tongue thingy smears and alters the crayon part of the drawing but the graphite is not affected. Meanwhile, to move the card around, there are two Spirograph wheels you cannot see clearly that mesh (usually) and keep the card turning semi-randomly too. Using a marker will obscure parts of the drawing and add other random squiggles, circles and blots.

Hm! Now that I explain it, it doesn't seem that interesting anymore. But this was my first try at kinetic sculpture and it sort of works. It did get quite a bit of interest (got me a free beer, too!).
