We made– and sold (!)– this art lamp a couple of years ago. It’s a life-sized hollow glass head glued to an aluminum base. Inside the head are two long, tangled, strands of multicolored christmas lights, each with a bimetallic “blinky” bulb. The two halves switch on and off quite irregularly in an animated effect that seems much more complex than the simple electronics should have produced. The end effect is a bit like neurons firing, or perhaps like the brain from a cheesy tv robot.

In this photo, JellyBean is sitting on the top of the bookcase with the lamp and is doing her best to blend in with the surroundings– cats are good at that.
