For my Halloween costume this year, I decided to turn myself into outer space - I sewed 12 individually addressable LEDs to my shirt, and programmed them to twinkle like stars. To complete the look, I designed and 3D printed a rocket ship that I could wear on my left arm.
This project is open source! On my website you'll find links to download source code, schematics, and design files: http://www.jeremyblum.com/2013/11/03/...
