I'm planning to make a machine that light randomly an area, with redstone lamps, at 4440. I don't know how to do it, so I'm going to pay 1k rupees to the person that designs the best, most compact random lighting machine. It has to fit in 4440 tier. Good luck!
Not around my building, only in one of the floors. The lights are in the ceiling, and they are supposed to light randomly.
