I was looking through some design sites at work and came across this radio ball concept. In a nutshell, the design of the ball acts as a self tuning radio that when rotated tunes to different stations, when you find the station you like you add a marker in to the ball and it remembers the station. When the ball rotates it turns the volume up and down. I really like cool concepts like this where people try comping up with some nice ideas. Ok the sound won't be fantastic, but as a fun project to build, it looks amazing!
