	A lot of people build these out of speakers, or at least on the same principle. I may be able to use the same principle as above - have two tones that are relatively prime. For 1024x1023 @ 60hz, we'd need 61440hz - not even breaking a sweat for audio. So 61440hz and 61380hz.		A lot of people build these out of speakers, or at least on the same principle.

	I can put either another laser or just an LED on the back side and pick it up with a phtotransistor. That should let me control the speed.		I can put either another laser or just an LED on the back side and pick it up with a phtotransistor. That should let me control the speed.

-Hook up a laser diode (or several) to something to move them around and turn them on and off in a cool way. I can't remember the name of the device, but it takes two mirrors and moves them independently to direct the laser.
