Summary

Oliver Gingrich presents three recent projects that merge interactive technology, projection mapping and environmental data. A member of an artist collective organising forums, exhibitions and workshops, he begins with a collaborative piece made at an Islamic digital art event, in which audience members' brainwaves drive projected cracks across a representation of the world, foregrounding CO2 emissions and concrete's role as a polluter. He then discusses 'Air', a real-time data piece about pollution, using a stream of local CO2 figures to visualise how emissions infiltrate everyday life, especially in deprived neighbourhoods. The third strand is a decade-long collaboration creating large-scale light, sound and projection environments, including a 2016 voice-visualisation at Union Chapel for its fiftieth anniversary and a Great Exhibition Festival commission inviting audiences to shape vocal harmonies. Finally, he describes a Tate installation about noise pollution in Vauxhall and Nine Elms, where visitors add their own projections to a sculptural soundscape. Throughout, Gingrich stresses the value of thorough preparation, controlled lighting conditions, community dialogue and using art as a catalyst for social change.
