How difficult/easy would it be to embed LEDs into a Rubik's Cube so that when solved, each individual face lights up? Answered
possible ideas: 1) individual circuits: one for each color/face. (if one face is solved it lights up even when rest of cube is scrambled) 2) one circuit throughout connecting all pieces. (this way it wouldn't glow unless entire cube was solved) Using some sort of conductive material in between the smaller cubes to complete circuit(s). Button cell batteries to power LEDs?
