Even as someone not very prone to gaming, I'm attracted to the idea of the Mag Gun controller. It works with multiple consoles, has logical controls, and looks like it'd make a first-person shooter the highlight of an afternoon.

There aren't too many details about how the Mag Gun works, but CrunchGear's Devin Coldewey has a theory:

The controller has a wide-angle camera in its tip, and to calibrate it, all you have to do it point it at the center of the TV. It then (if my analysis is correct) simply tracks the luminance image of the TV (it's a distinctive rectangular shape, obviously) and uses that to determine where the gun is pointing. That's very smart! It has all the same drawbacks and advantages of the Wiimote, which just uses IR instead of the TV's visible spectrum.

The controller has just made its way through the FCC, so it'll still be a while before we can get our hands on it and play. [CrunchGear]
