I wanted to experiment with the idea of “minimalistic skeuomorphic” interfaces. I wondered what would an mp3 player with only one button or only one knob would look like, so I decided to make a mockup of an application that was just that – an mp3 player that had only one knob for all of it’s functions. The switch on the bottom right corner changes the functionality of the knob between searching a folder, searching in the track and adjusting the volume. Pushing the knob would either select a folder or play/pause a track.
