If you happen to be venturing somewhere noisy or somewhere very quiet, it's likely that you won't hear your cell phone ring. That's just the way it goes these days - there are plenty of places where ringing phones just aren't welcome. These light charms, from UK designer Mathmos, are the ideal accessory for anyone who wants to be alerted to their cell phone ringing without having to keep an eye on it all the time. The light charm senses when a call is being received and flashes to let you know.
