Seeing Through Walls is about to get cheap and light
 

Researchers at MIT are experimenting with a system called Wi-Vi, which they say can track moving objects through walls by using the inexpensive, nearly ubiquitous wireless system. Wi-Vi could be built into a smartphone or a special handheld device and used in search-and-rescue missions and law enforcement, according to Dina Katabi, the MIT professor who developed Wi-Vi along with graduate student Fadel Adib.
