Shoogle is a technology for communicating a phone's (or other mobile device's) contents passively using touch and sound. Users can shake their phone to find out how many messages they have and who they are from, in the same way you might learn how many objects are in a jar from shaking it, or how much change is in your pocket from the way it jingles when you walk. It even lets you experience your battery life in the same way you experience how full a bottle is of water. Neat, say I.
