WiFi-blocking wallpaper

Peter Rojas
Stealth Bomber

Maybe they're figuring that this wireless-thing has more legs than the whole building-weapons-thing, but a British defence contractor has created this wallpaper that can actually block WiFi signals and confine them to certain buildings and rooms so you don't have to worry about other people trying to free ride or hackers trying to break into your wireless network.  The wallpaper uses special Frequency Selective Surface panels similar to the materials used in the stealth bomber, and comes in both active and passive varieties, so you can switch off the WiFi blocking at whim. No word on when it'll come out commercially, but it'll probably have Pentagon-style pricing.
