A friend of mine and I temporarily hacked my qube to produce less light
at night using simple photoresistors we got from Radio Shack. Their
behavior is to produce less resistance when you shine light on them, so
you can just put one of them in series with one of the LED wires.

The only problem is putting the photoresistor on the outside of the
qube... without going out through the expansion slots at the back, you
pretty much have to drill a hole through the case and internal, metal
qube that the hardware lives in. That's why I removed all the stuff
after the testing we did (which amounted to turning off the lights and
watching the LEDs get dim.. ooooohh...).
