Marina: we even use our car in the performance, in '77, for the Paris Biennale in the front of the museum we made this piece called Relation In Movement, which Ulay is driving the car and I had the megaphone out of the window, and I would say the numbers of the circle as we was passing, because it was just going in a circle, on and on and on. The idea was the car collapsed or we collapsed. and after 16 hours, the motor burned out and created this minimal trace on the marble as a black circle. For us each circle was a kind of imaginary year.
