A fantastic prototype from Skrekkøgle, Plugg plays on the phrase “put a cork in it”, with a cork literally turning the digital radio on and off. In a world where physical buttons are taking more and more of a back seat on electronic devices, pull the cork out and the radio turns on, then pop it back in to turn it off. Volume and station switching obviously require a little more control, but such simplicity is so great to see, and a really great innovation in design.
