Shirt detects cellphones

Check out this unique shirt which is capable of detecting a cellphone that rings, making it perfect for settings where you put the phone on silent or vibrating mode, and yet need to attend to the call urgently. Operas would be a good example as there is nothing quite like the din of a ringtone to spoil the current performance. This cellphone detecting AwareFashion shirt by Richard Etter comes with a pocket, an antenna, a small circuit board, button cells and fiber optics that will sense all switched on phones in the vicinity. It will glow unobtrusively whenever it detects a phone nearby, where you can choose from glowing green, red, yellow, white or blue colors. Perfect for opera houses to pick out culprits who fail to turn off their handset.
