Supported by Creative BC’s Interactive Fund, Halo is a large-scale, light-based interactive installation, whose distinct sculptural shape, bright colours and vibrant animations evoke strong synesthetic experiences.
Conceived by Alex Beim of Tangible Interaction, in collaboration with Travis Kirton, the piece was created to emphasize collaboration and limitless creative possibilities. Halo not only employs several open-sourced programming interfaces, but the sculptural component itself is highly modular and open to reconfiguration. For LIGHT: Illuminating Science & Art, a new specially designed interaction allows the public to create deceptive visual effects that are in contrast with the sculpture’s objective reality. Using two rotary encoders mounted on columns—one to control motion and the other to cause delay, circular patterns of coloured light can be manipulated across Halo’s seventy-two LED rings. The resulting visual illusions are unique to each participant, as is their perception of what they create and see.
