Korean augmented reality firm Zenitum recently demonstrated this neat Space InvadAR project for Android devices, in which you play from the perspective of an "extra-orbital fighter pilot", moving around your handset (an HTC Desire in this video) to aim at invading Zengi aliens who are trying to destroy the Earth, or at least a printed photo of the Earth that serves as the AR marker.

Zenitum plan to put out the game on Android Market for $25, which seems a bit expensive (and it's fairly simple compared to some other titles like Georgia Tech SCAD's augmented reality zombie shooter ARhrrrr). The company expects most of Space InvadAR's buyers will be "augmented reality junkies", though.
