Mount 200 digital cameras on tripods and place in a circle, facing into the centre, in a gallery room.
Set them to auto.
Connect each one with a USB cable to a Macbook, lay the macs on the floor in a larger concentric circle around the cameras, screen up, showing what the cameras are shooting in real time.
Set each mac up as a separate IP and register them all as each others followers on social network sites, set the dashboards up to register each update automatically.
Start shooting, the piece ends when the batteries run out.
