Taking those electroluminescent wires to a whole new level, a company called Darkside Scientific has created a sprayable paint called LumiLor that casts a uniform fluorescent glow whenever a current is applied. So it can be used to cover irregularly shaped objects with ease, and as Boing Boing points out, it has the potential to revolutionize Burning Man.
Presumably it's not the kind of paint you're going to want to spill or accidentally inhale, so LumiLor doesn't just sell it in cans to the public. And given the unique ways it can be used, I'm assuming the power source needs to be specially engineered and integrated for every application. But it would totally be worth all the hassle. Imagine a room with every wall covered in this paint that wouldn't need an ugly chandelier, unsightly lamps, or even a window for illumination. That's the dream, right?
Update: A representative from Darkside Scientific reached out to let us know that the LumiLor paint is as safe as any other household paint you can buy. And the primary reason it's not sold to the general public is because the quality of the results relies on the quality of the application, and this allows them to train anyone who applies it with the proper technique.
