Performance artist Stelarc has been engaged in various investigations of the body, the most well-known and dramatic of which are his body suspensions. Performed in various sites and situations around the world — including Japan, USA, Germany and Australia — Stelarc pierces his skin with hooks attached to load-bearing strings to suspend his body in different positions. Not all the performances have been static; his body has swung, spun, swayed and propelled itself. In some instances, Stelarc incorporated the amplified sounds of his heart beating and muscles stretching. In these documented performances, Stelarc explored what it means to be human, examining how the body is the site of human experience in a changing world affected by new technologies.
