Hand of Man by Christian Ristow

"The Hand of Man is a large hydraulically-actuated human hand and forearm, capable of movement in all the same axes as a human hand and forearm, and fabricated from steel and stainless steel. This enormous Hand is controllable by way of an ergonomically accurate "glove". Anyone who wishes to operate this gigantic and powerful Hand need only insert their hand into the glove controller, and any motion they produce from the elbow forward will be accurately and quickly reproduced by the large machine Hand. Participants experience the tremendous thrill of power and control as they lift, twirl and crush objects of their choice, such as cars and pianos." [Hand of Man]
