The shape for the radio object should be like the one in the model. Or at least similar. Very few controls, to not confuse the user about functionality (few controls = few gestures). I’d like the shape to be roundish, a little like the colored iMacs. The object should not feel too technical, because there is already a big step between the current radios and gestured controlled radios – which is based on technical changes. By making the object rounder I intend to increase the feel of talking to something «smart», something alive.
