Remote control for your facial expressions

Alec Smecher built a wireless electronmechanical system that enables him to robotically raise and waggle his eyebrows via remote control. Because, you know, he could. From MAKE:

Beyond its obvious practicality, this project makes a great introduction to DC motor control, infrared remote control, and moving from working with an Arduino to working with the bare ATMega328 chip. These concepts are combined with some minimal extra circuitry.

The end result will be a great conversation piece, that is" if you don't stab your eye with a toothpick. My implementation supports calibration, independent control of each eyebrow, and a 1- to 9-way waggle feature. Expressions vary from skeptical to shocked to very, very shocked.
