Jean Tinguely’s performance Homage to New York took place in MoMA’s Sculpture Garden on March 17, 1960. For the event, Tinguely and Bell Laboratories engineer Billy Klüver designed a monumental kinetic sculpture—a "suicide machine"—designed to implode with the push of a button. Drawn to the collaborative process of building the machine, Rauschenberg helped Tinguely and Klüver gather the materials and put them together. Rauschenberg contributed his own kinetic sculpture, Money Thrower, a small electric heater that was ignited by gunpowder in the seventh minute of the performance, producing a flash of light and releasing a dozen silver dollars that spewed out into the audience.
