You'd know what your dog is trying to say before he ruins the carpet with the LED Dog Tail Communicator, designed by James Auger and Jimmy Loizeau. It's a part of the designers' Augmented Animals project, which envisions a world where technology is also acknowledged and utilized by animals. The Tail Communicator measures a dog's WPM, or wags per minute, and translates that enthusiasm into a message a string of words that hover in the air like one of those LED-arm clocks.
It's just a concept being shown off at the Modern Museum of Art in NYC for the Elastic Mind exhibition, but who knows — maybe you could rewire the device and turn your dog into a walking clock.
