Use two fluctuating infrared sources to unlock the Wii control panel, as my son showed me.

Hmmm, what kind of contorl panel is that?

Why not just make two infrared LEDs emit :)

btw, here's some 3D position-sensing fun: make an infrared emitter >20Hz, and connect two phototransistors to your soundcard's input. You can measure the distances now and triangulate :) (though 3 phototransistors are ultimately required for real 3D, and good half-angles of emitters and receivers)

Candles are cheaper?
I recall teaching him how to gain credits on arcade machines using the sparking device from a gas powered hot water system, I think we're not even but its still worth something?
Actually, lets be clear, this is more "how to use a Wii without a Sensor Bar device".
