I built this shirt to experiment with wearable computing and electronic textile technology and realized along the way that the basic materials were actually quite easy to work with and there was lots of room for creativity and innovation at all levels, so I was inspired to write up this do-it-yourself guide. Everyone should be playing with this stuff! It’s great fun for geeks and divas — build yourself a sparkly fashion accessory and program it with the Game of Life or other hacker animations. You’re guaranteed to turn heads whenever you’re out on the town.
