Mark Shepard is developing “Tactical Sound Garden” Toolkit (working title). The concept is to create an open source platform for cultivating public “sound gardens” within urban environments.

The Toolkit would enable people to “plant” sounds within specific urban locations using their WiFi enabled mobile device. It draws upon the proliferation of 802.11 wireless (WiFi) access nodes in urban environments as a free, ready-made, location-aware infrastructure for alternative forms of social expression.
