Festooning your clothes or costume with lots of glowy lights is fun. Making the glowy lights survive hours or days on end of dancing in sweaty raves or muddy festivals is harder. In this talk I discuss several ways of being a walking lightshow, the unfortunate lessons I learned over years of trying them out in the real world, and some attempts at avoiding these failures in future. [Specifically I will cover: chemiluminescence, electroluminescence, UV reactive materials, LEDs, things to consider when making light-up clothing, surprise 100v shocks and how to avoid them, and how to cheat at syncing to the music.]
