Flip Frogs is a curious project from 2004 by Meridith Pingree:
rainbow ribbon-wire, green LEDs, MDF, conductive nickel paint, backflipping plastic frogs, aluminum foi.An image of water in conductive paint covers the surface of the shelf. Every painted line feeds into one of the strands of rainbow ribbon-wire, either positive or negative, which intersect on the wall with an LED. When people play with the foil-footed frogs, they are crossing wires and activating various locations on the wall with limited control.
Why do I blog this? an intriguing example of location activation of toy-like artifact. A model for a weird wires-apparent board game?
