I remain detached and distant, but it is under my eyes and my orders that the work of art must create itself [Klein directed on 9 March 1960 for the first time nude models who were painting the walls with their moving naked bodies, he called this "Anthropometry"]. Then, when the creation starts, I stand there, present at the ceremony, immaculate, calm, relaxed, perfectly aware of what is going on and ready to welcome the work of art that is coming into existence in the tangible world... Hours of preparation for something that is executed, with extreme precision, in a few minutes. Just as with a judo throw.
