The Wiimote certainly changed how video games are played, but can all that controller wagging be used to control your TV as well? This concept "Remotion" remote control posits that yes, yes it can.
While it looks like a fancy dustbuster, it uses motion to control your TV. Shake it up and down to adjust the volume and move it side to side to flip through the channels. But with today's remotes having tons of buttons for things like picture-in-picture and swapping sources, I'm not sure something so simple would fly.
