Grisbug is like a hexbug, only with programmed features. It is programmed to blink its eyes when a flashlight shines on it. When the flashlight comes closer, grisbug ‘wakes up’ and the eyes glow continuously and the motor runs. When the flashlight is removed, grisbug still glows and makes noise for several seconds before going back to ‘sleep.’

(NOTE: In the video, it appears that on of the LED ‘eyes’ isn’t working. It is, but it’s very dim.)

What’s next: fitting it into a smaller, lighter enclosure. Then I’ll think about adding user programmability.
