Glass Full of Radio

Have you ever tried this: take a glass (wine glass is better) and fill it more than half with water, then dip your finger in the water and rub it on the rim in a circular motion.
Soon a very peaceful rhythm, more like Buddhist chants, can be heard.
Playing on this physics is the radi_O, a concept radio that hopes to keep the intuitive bond between the music-box and humans, intact.
And just like the finger on the glass, a good swirl on the radi_O rim controls the volume and the music station. Awesome!
