To get you in the mood for NMF2013 Patrick Borgeat (@cappelnord) has designed and created Interactive Networked Web Audio Experiences!
A set of small web toys containing a distinct musical experience, all controlled by the same interface, which explore the superimposition of different sequence lengths. Interaction is shared between all connected users and state is preserved for upcoming users. This way people from around the world can share their experience and leave trails for upcoming users to discover.
The instrument is available online NOW. Click the link to start: http://nmf.cappel-nord.de/. Have fun!
