"The brain geniuses at Fraunhofer are back on the scene with a security device that takes the window alarm to the next level. The Vigilant window sees the ol' glass panel coated with a nanoparticle material which converts light into fluorescent radiation. When the system is switched on, a UV lamp is aimed at the window, which is outfitted with sensors along its edges. As long as the lamp is unobstructed, everything is goldie. However, if a cat burglar should come by in his trademark all-black out fit and obstruct the beam, the alarm is activated -- sending your elite security team into action. If you don't have an elite security team, perhaps you can send your T-34 to snare him in its net. Either way, it's clear they messed with the wrong folks this time. A prototype already exists, no word yet on when this will become available.[Via Oh Gizmo!]"^^<http://www.w3.org/2001/XMLSchema#string>
