I will be premiering a new audio-visual installation titled PiAV at this years International Computer Music Conference in Athens, Greece from September 14th through September, 20th 2014.

PiAV is an immersive multi-sensory environment created using twelve Raspberry Pi computers. I have created a portable 8-channel sound environment using custom made speaker boxes, networked Raspberry Pi computers, OSC and Pure Data. In addition I have created a 2-channel video-feedback and motion tracking system using four Raspberry Pi computers, Raspberry Pi camera modules, OSC and a custom Python script. Since the Rasperry Pi computers are so small the whole system is completely portable and only requires a gallery space, a wifi connection (I can bring an ethernet hub if necessary), two video projectors and power.

PiAV is an installation that can be observed and is also participatory but in a subtle way. In its more static form PiAV makes use of quiet sin waves that are tuned in a unique just-intonation scale and activate the space through subtle beatings. Meanwhile two channels of abstracted video images are generated using very simple digital processing inspired by traditional analog video feedback techniques. The system is cross-polinated whereby the ever-changing combinations of pitches (clusters) influence the video feedback system and the colors and the amount of motion within the video influence the audio parameters creating a meta feedback system. Two additional Raspberry Pis are used for simple motion tracking of the gallery space. When viewers/listeners enter the environment their movements are tracked providing another subtle input to the audio-visual system which cues interaction and participation.
