Arboreal Lightning is a vast site-specific interactive lighting installation weaving through the filigree architecture of the Camden Roundhouse.

It transforms sound and gesture into an immersive luminous experience, its tree-like fibres shimmering in response to music and movement Bundled individually addressable LED strips burst from the stage and soar above the performers, their branches twining along the Roundhouse structure and into the heavens as a form of sculptural, bifurcating video. The occasional strand stoops to greet and listen to its visitor, with 6 microphones distributed throughout the space, feeding the tree with the nectar of visitor interaction.

The project was commissioned from atmos by Imogen Heap as the centrepiece for the Camden Roundhouse's Reverb 2014 Festival - a smorgasbord of contemporary composers, with an emphasis on technological innovation.  It was conceived and designed by atmos, programmed by Adam Stark, and built by a small army of amateur volunteers.
