When you're driving your car there are times when a single finger gesture can perfectly express your sentiments to a fellow vehicle operator. Although this is a relatively efficient form of non-verbal communication, we would like to present a device that brings some technology to the table.

The Driving LED Emoticon is a battery powered, wirelessly controlled message sign that can be attached to the rear window of your car via the included suction cup. A remote control unit is kept in the front of the car (fixed to front window, dash, or laid in a storage compartment) to activate the messages by pressing one of its buttons.

It can display any one of five different messages - 'smiling face', 'sad face', 'Thanks', 'Back Off' and 'Idiot'. We will, of course, leave it up to you to decide which of these messages suits your particular situation - but we do think it's nice to have a device that allows you to more clearly express yourself to other drivers.
