London design duo Studio Ayaskan has created a clock, which rakes sand in hypnotic, concentric circles to mark the passage of time.
The Sand project is a nod to Japanese rock gardens, called karesansui, in which sand is shaped into patterns to mimic the appearance of water rippling.
It consists of a circular, sand-filled platform and a single hour hand. In the daytime, from midnight to midday, it draws ripples in the sand.
Then, for the second half of the day, the hand flattens them out again in order to begin another cycle at midnight.
