Awnwalker

Make a vibration-powered walking toy

A bristlebot that walks like a grass seed. A wild oat awn has stiff backward barbs, so every shake ratchets the seed forward; this body stands on eight raked legs, and a coin vibration motor with a CR2032 in its hollow back makes it scurry across the table.
