Blinkybugs are “small, simple, electromechanical bugs that respond to stimulus such as movement, vibrations, or air currents”. All it takes to make your own is a little bit of wire, a pair of LEDs, a coin-cell battery and a few miscellaneous electronic bits. When “stimulated”, the eyes blink in “interesting rhythmic patterns”, and your toy comes alive.
