For when flipping the bird or giving a friendly wave takes just too much effort, one company now offers the Drivemocion, a device that mounts to the rear windshield and will display one of many differ emotions to drivers behind. Was that car nice enough to let you merge on the freeway during rush hour? Greet them with a smiley face. How about the asshole who's riding your tail? Give them a digital bird. Cutie in the car behind you? How about a wink and a smile.
The device is battery powered and has a control mechanism that can be mounted on the dash or anywhere else. It's available for $50 or so from Au-my. It'll be a great addition to your fake bullet holes and truck nuts. [Product Page via Giz]
