In the pantheon of corny gags — rubber chickens, whoopee cushions and so forth — there’s a special place for googly eyes, that staple of childrens crafts and tacky “You’re HOW old?” birthday cards.

We’ve done realistic eyes before…it’s the default program that ships on the HalloWing. Suppose we desire something more…zany?

HalloWing has an accelerometer and can respond to motion…let’s make it into a googly eye!

Everything needed for this project is built into the HalloWing board, no extra components are required. (A battery can optionally be added to make it self-contained and portable.)
