Erwin Wurm, sculptor

I love how Erwin Wurm engages gallery and museum goers by asking them to follow instructions and create art or sculpture themselves. More often than not, his sculptures do not exist without the aid of a strangers' body. One of his largest projects is called "One Minute Sculptures" where he asks strangers, people on the street, CEOs of companies, etc to do something silly and hold it for one minute while he takes a picture. Sometimes he will tell them exactly what to do or only vaguely give them hints via some props.
