A clock has been designed by the London based design studio Ayaskan, which uses sand by creating ripples to map the passage of time. The clock is an ode to the Japanese Rock gardens which create a similar pattern out of sand to create a water ripple effect. The clock works with the help of a single hour hand which draws ripples on the sand filled platform from midnight to midday. While the second half of the day, the hour hand clears the ripples and flattens it in order to start its cycle again from midnight.
