"Event Horizon" by British artist Antony Gormley

"Event Horizon" by British artist Antony Gormley consists of four cast-iron and 27 fibreglass casts of his own nude body,
placed at ground level and poised on the edges of buildings. It was exhibited in London in 2007 and in New York in 2010.
It may have taught the young man in the green sweater something he won't learn at Touro College of Osteopathic Medicine.
