Flow is an audiovisual HTML5/WebRTC experiment which uses a simple pitch detection algorithm on your microphone input in real time to guide a line through space. Note: The only officially supported browser is Chrome. If you haven't already done so, you need to enable the "Web Audio Input" flag in "chrome://flags".
This experiment links users in real time via Socket.io and Node.js, so that each user can see each other user, creating some form of user-driven digital artwork in each browser window. Your microphone data is not transmitted, only the calculated frequency value.Source Code
