Anyway, cool invention, I could imagine using them as surround lights. Like, when you go into a pitch black forest, you could command them to keep a certain radius of light around you or something. Smart lighting admittedly, that removes their pixel purpose, but whatever.
Keeping the pixel purpose, it could be interesting to add sensors to them, like radiation sensors, and make them create visible colour maps over a terrain. It'd give scientists a wet dream.
