The Ripple Clock is a mechanical clock made of ceramic. Placed horizontally, the clock’s second hand taps the surface of water poured into the ceramic, generating ripples every second. Time is often measured and expressed as circulation by modern mechanical or digital clocks. However, time not only circulates but ‘accumulates’, as the past shapes the present and the future – Kensho explored the ways in which such a conception of time could be embodied. The Ripple Clock succeeded in materialising the accumulation of time through the behaviour of the water’s surface, showing the continuous overlap of the ripples produced from the past to present.
