--Wondering if anyone found anything flashy and kewl. Here's a cc of what I found and posted on the Art Car tribe:

--Hiya gang! Probably in your local mall you've got something like Spencer Gifts; i.e. the joint that sells all the lava lights and the silly pull-my-finger farting Homer Simpson dolls and the like, yes? In the back they've got a section of "party" stuff; i.e. strobe lights, black lights, etc. Tonight, during the post Xmas sale I snagged a couple of 18" blacklight fixtures. They're AC but so what; one inverter later and you're running 'em off a car battery. They were incredibly cheap at $14.95 apiece and they also have a fairly substantial translucent green da-glo plastic enclosure for the guts, good enough to see any obvious problems. The housings also have enough empty space within for hacks you might want to add.
--I'm hoping to put one somewhere on "Short John Silver", maybe keeping the other as a spare if needed. Now I'm looking for ideas on what to illuminate with it.
