going to redecorate my room with a plasma/glowing/physics theme to the best i can afford. i've a lubbeen plasma ball, some lasers, a smart mirror. gonna try to get (or make) tesla coils. gonna glue my rpi to the wall and put the wires alongside it. what else would you guys add?

i want to add a projector maybe. is there anything else you guys would add? maybe a cool lamp? also, any ways to add in another rpi/arduino other than the smart mirror that you guys can think of?
