Cellphone Accessory: Signal Cell Phone Adviser

If you’re expecting an important cell phone call at the office and you don’t want to disturb the rest of your workmates with your raucous ringtone, why not use this handy little blinking cup? All you have to do is place your cellphone inside it (with the ringer off of course) and the frosted plastic cup lights up whenever you get a call. The radio waves from the incoming call trigger the light show. While not a thoroughly new concept, as we’ve all seen key chains that do pretty much the same thing, those little key fobs are usually connected to your phone, and end up in the pocket rendering them pretty pointless. Not exactly a necessity, but it would make a pretty neat $21 gift.
