Wow, talk about your mileage may vary.

I've generally found BRC to have more UV lights in use than anywhere else. We used it in our camp's public space (we've been just off Esplanade in the last couple years), as have most of our neighbors. I don't normally dress for UV, but see it in use regularly at camps, art installations, and mutant vehicles throughout the playa. Even if I wasn't shaving my head I'm not sure I'd use that stuff though, it seems like something that could get to be more of a mess and cleanup hassle than it's worth. You might want to look around for UV makeup that you can use as accents, or look around at some of the LED, EL-wire, or fiber-optic stuff you can wear in your hair (or on a hat). If you get some, you can try it at home. Use it (and take pics, of course), then see what it looks like hours later, and the next day. Make sure to work up a sweat (exercising, dancing, etc), and see how it holds up.
No worries, it could go in Power & Illumination, but I think it fits well in playawear too.
