Microsoft's Xbox 360 Kinect motion-sensing add-on may be perfectly kid friendly, but we're pretty sure this latest hardware hack would scare the bejeezus out of any little ones that may come across it.
Using a Pufferfish spherical projection display and the motion contoller, plus a fair bit of tech-y know how, these hackers have made a Lord of The Rings-style all-seeing eye using the gaming gear.
Here, the Kinect tracks people's movements around the room, with the information pumped to the projector, making it seem as if a giant eye is watching you.
Due to the limitations of using a single Kinect sensor, the eye can only track people within a 180-degree angle, but we're sure it wont be long until they hook a second sensor up to complete the nightmarish hack in all its 360-degree creepiness.
Check it out in the video above.
