Michael Flynn creates hands-on interactive installations that are fun and eye-opening. He displayed his Cooperative Phonograph at World Maker Faire in New York this past weekend.
Stepping inside a giant air pressurized Mylar dome, you are faced with an intriguing disk that you approach on a red carpet. The large disk is mounted slantwise on a stand, its central mirror reflecting the silvered inner surface of the Mylar dome.
The disk looks like a giant vinyl record, and that gives a hint to its purpose. Watch the video below and see what it does.

HOW DID THEY DO THAT
Michael explained to me that he used a water jet CNC (computer numeric control) to cut an audio signal into the edges of the metal disk, much like sound is recorded on a phonograph or record.
