WiVi Will Let You See Through Walls
This could soon be built into your cell phone.
MIT professor Dina Katabi and graduate student Fadel Adib have announced WiVi, a demonstration of a technology that uses WiFi to allow a viewer to “see” a person moving behind a wall. (WiVi stands for “WiFi” and “vision.”)
Previous work demonstrated that the subtle reflections of wireless inter signals bouncing off a human could be used to track that person’s movements, but those previous experiments either required that a wireless router was already in the room of the person being tracked, or “a whole truck just to carry the radio,” said Katabi.
The new device uses the same wireless antenna as is found in a cell phone or laptop and could in theory one day be embedded in a phone.

I think it'd be kind of cool to have this, BUT I really do not expect to see it anytime soon with all of the Privacy issues around.
