Art Exhibition Closed After 3 Patrons Fall Ill Authorities have temporarily shut down a room-sized art installation in Pittsburgh after three visitors reported seizure-like symptoms. The Pittsburgh Tribune-Review (http://bit.ly/18jk44i) says the work titled "Zee" by Austrian artist Kurt Hentschlager opened Friday in downtown Pittsburgh. An 18-year-old woman was treated at the scene Sunday afternoon after reporting seizure-like symptoms. District EMS chief Paul Sabol says she was the third person to report feeling ill. Before entering, patrons must sign a waiver that describes the exhibit as "intense stroboscopic light in combination with thick artificial fog, resulting in a loss of spatial orientation." Those with photosensitive epilepsy, breathing or heart problems and other issues are warned not to go inside. Sabol says changes could be made before the exhibit reopens. Hentschlager couldn't be reached for comment.
