The Visual Microphone

If this video on The Visual Microphone doesn't blow your mind, you're too far gone into pessimism. MIT researchers have used high speed cameras to capture the vibration of everyday objects and re-interpret those movements back into the sound waves that caused them. Basically, everything is a microphone and now they have a tactic to retrieve those "recordings." The results are, obviously, distorted but given the method of retrieval they are wildly clear.
