Tully Jagoe of Adafruit Industries shared a tutorial on making an LED eye prosthetic as an addition to Halloween costumes or for cyberpunk fashion. Because the LEDs point the light forward and act as a headlamp, the wearer can see easily.

This is a very simple project you can use to help make cyborg, demon, alien, or any other glowing eyes for your costuming needs. This will require some patience and a steady hand, and a couple of hours time.
