Time Piece (Martian Deadbeat) is a clock built to tick with every Earth Second. Yet the pendulum is manipulated to swing as it would on Mars: because the gravity on Mars is weaker, the ticking is about 20% slower. The work is inspired by sci-fi. Mars is a metaphoric planet; many stories take place on its fantasized ground, with the intent to paraphrase terrestrial situations or dreams. The sculpture therefore beats to the time of imagination, transferring the martian ticktocking to Earth. It also reminds us that a time standard such as the Second is relative and that the shape of time we are used to, made of minutes and hours of a fixed duration, is nothing else but a convention.
