Crossed bedside lamps turn each other off and on

Ry4an sez, "Today's maker project was a pair of bedside lamps that switch one another. The effect is really jarring because the switches are so near the bulbs they'd normally control." I love this — it's just annoying enough that you can imagine it appearing unintentionally in, say, a hotel room (the most notorious source of terrible lighting controls in the developed world), and yet perversely pleasing.
