The Mogees Kickstarter project is in its final day, and already is well over its fundraising goal.
Mogees is a software + hardware system, designed to turn anything into a playable musical instrument.
Mogees consists of a mobile app and a small sensor that detects and analyses the vibrations that we make when we interact with the objects around us. It uses a special sound technique to alter their acoustic properties so as to make them musical.
See the Mogees Kickstarter site for details.
