Who needs Tin Foil, we’ve got Paint

If you’re bothered about the security (or lack there of) of your Wi Fi connection you’ll soon be able to paint a solution thanks to EM-SEC Technologies Wi Fi blocking paint.

The paints is said to block various electromagnetic transmissions so along with Wi Fi it could also be used to block mobile phones. As well as the obvious security and social benefits (no more annoying crazy frog ring tones in the middle of a movie), it could also be great for pranks, imagine a mate trying to troubleshoot his Wi-Fi connection after you helped him decorate.
