As you look at the radi_O device, the image of wine glass music may pop into your head. That is because radi_O was inspired by that. Looking like a drinking glass filled with water, this contraption calls for you to actually run your finger along its edge to control it.
Designed by Sunyung Yang, the radi_O introduces a very tranquil and zen quality to musical experiences. Although FM-AM radios can be quite typical-looking, this concept design really introduces a new aesthetic.
In fact, the radi_O concept advocates a more intuitive and interactive experience between user and device, as though it were an instrument itself. Basically, by running your finger along the rim, you are able to control the volume and station.
