In the past few months, we have covered a bunch of cool LED eye projects from crowdfunding sites. You could always make wearable lights if you know your 3D printing and electronics. Adafruit has shared a guide that shows you how to do just that. It was inspired by the LED eyelashes project.
You are going to need two packs of LED sequins, 12mm coin cell, wire wrap, and a few simple parts to get started.
