Obeyken writes “Electronic / kinetic bug art. I build these small, insect-like sculptures with simple motion-detecting “antennae” that respond to various stimulus such as movement, vibration, or air currents. When picked up, handled, or otherwise stimulated, the bug comes to life as its LED eyes blink rhythmically. I have one sitting on my monitor right now that blinks as I type. They’re constructed from LEDs, bits of wire, guitar strings, and coin-cell batteries (the PCB battery holder is the bug’s “body”). My original plan was to deploy them throughout San Francisco as a sort of “electronic graffiti” but thus far they haven’t survived too long in the wild…” Link. You could also make your own, the design is the how-to.
