Apparently software developers are working on a cell phone application that can "see" through walls.
The 'Real Space See-through Mobile' software comes from KDDI's R&D laboratory and Tokyo University and is - you'll not be surprised to learn - still just a prototype.
Although we weren't able to see it in action, we can tell you that it is supposed to be able to judge its surroundings, including those on the other side of a wall, using six different sensors. Three acceleration sensors combine with a similar number of geomagnetic sensors and a GPS chip to work out exactly where the phone is and in what direction it's pointing.
Using some sort of digital voodoo, the software then uses OpenGL to draw on the screen what it has 'sensed' is in the immediate surroundings.
Awesome, locker room spy shots without having to disguise myself as a water fountain!
