収束ゾーンでのライフ: Life in the Convergence Zone

 
low light and normal light

Friends held a solstice party and traditionally it's held in the dark except for lights people bring, so I made hidden (in my cuffs) LED ultraviolet light emitters ("blacklight") and drank drinks mixed with tonic water so they would fluoresce.

Also I could point at things and they'd glow. (Sometimes.)

It's much more violet than it looks in these pictures, I'm not sure what's up with my camera making it so blue. But it might be because I see ultraviolet as, well, violet, but more.

(I'm always the one playing with UV at these things, because I'm the one who can actually see it. But everyone can see the other bits, and also, these LEDs also put out a bit of just straight up visible violet-range light, probably so people with conventional vision can see they're on.)
