"We [ Tristan Tzara and Jean Arp ] found him [Picabia in 1919, in his hotel in Zürich] busy dissecting an alarm-clock.. .Ruthlessly he slashed away at his alarm-clock down to the spring, which he pulled out triumphantly.. ..and soon impressed the wheels, the spring, the hands and other secret parts of the clock on pieces of paper. He tied these impressions together with lines and accompanied the drawing with comments of a rare wit far removed from the world of mechanical stupidity. He was creating antimechanical machines.. ..machines of the unconsciousness.."
