Perhaps more cool than actually useful, one enterprising New Zealander, RumblePackNZ, has used his Call of Duty IR googles (which came with the deluxe limited edition of the game) to see how the Kinect works with its infrared light beams.
The end result is thousands and thousands of dots covering the three-dimensions of his living room, which the device maps to create a 3D playing stage. Either that or he suffers from a serious case of dandruff.
And while his technology can be faulted, it's easily the best use to be made from a game giveaway that we've heard of at Pocket-lint.
Do you have a better use for something you've got free from a game? Let us know in the comments below...
