Known for artwork that favors experience over objects, Haroon Mirza was inspired by a mind-boggling proposal which he has made into the central concept behind his current exhibition at Chelsea’s Lisson Gallery. Introduced in a British sci-fi novel from the 30s and advanced in the 60s by the physicist Freeman Dyson, the Dyson Sphere is a series of orbiting platforms erected around a star to harvest solar energy. Mirza creates a mini version at the center of the gallery; a ring of solar panels collects energy from the halogen lights at center, providing energy to power various artworks around the gallery, including a terrarium of hallucinogenic cacti and a simple machine that plays a set of drums. (On view in Chelsea through Feb 12th).
