The Burble is a massive structure reaching up towards the sky, composed of approximately 1000 extra-large helium balloons each of which contains microcontrollers and LEDs that create spectacular patterns of light across the surface of the structure. The public, both audience and performer, come together to control this immense rippling, glowing, bustling ‘Burble’ that sways in the evening sky, in response to movements of the long articulated interactive handle bar at the base of the structure. The ephemeral experience exists at such a large scale that it is able to compete visually in an urban context with the buildings that surround it.
