Sometimes a gesture says more than a thousand words. Especially when you’re driving and that gesture doesn’t employ all the fingers available. But… that’s so low tech… and the driver behind you might not get the full view to appreciate it. Beside, there’s no gesture for saying you’re happy.

Luckily someone thought about those techy drivers and invented the Driving LED Emoticon. It’s basically a LED sign you can attach to your rear window (via the suction cup included) and can control wirelessly. It can display 5 messages: 2 faces (smiley/frown) and 3 texts (”Thanks”, “Back Off” and “Idiot”). The nasty messages outnumber the nice ones, but… let’s admit it, most people only feel like comunicating with their fellow drivers when they’re pissed off.
