"The Signal Cellphone Adviser adds a splash of polite ring notification to your desktop by way of a radio wave-detecting cup. Turn your ringer off (not a must, but it sort of defeats the purpose otherwise), drop your handset in the small opaque-sided cup, and whenever a call comes in, LED blinking action! We've seen similar devices before, but they were typically hanging on key fobs which are usually in your pocket, making them kinda useless. If this device had a charger built in -- which from all signs it doesn't -- we would seriously have considered giving it a spot of honor on the desk. Still, not a half bad gift for $21.[Via Core77]"^^<http://www.w3.org/2001/XMLSchema#string>
