Chintan Upadhyay (b.1972) thrusts you into a brave new world of cloned babies that’s chilling in its grim unreality. But in this sculpture they neither dance nor pose with fiendishly cute gestures because they’ve been devoured by a billowing cloud from which stare out their unseeing eyes. Is it an encounter with extra-terrestrial forces? Or a mushroom cloud blooming with radioactive particles? Or a memorial to violence, with the severed heads of his smart alecs? With dark shadows hemming in a circle of strident light beneath it, uneasy suggestions are awakened by this doomsday metaphor.
