It’s not digital. There are no connected apps to interact with. The movement is restricted to the concise circular arc of a single hand. Yet the Sand clock by Studio Ayaskan in London (Bike and Begum Ayaskann) might be the most mesmerizing timepiece we’ve seen in recent memory. A meditative play on the landscape art of kare-sansui – the artfully raked Japanese Zen rock garden – Studio Ayaskan’s sand clock rakes across a bed of sand, leaving ripples in the sand to represent each hour of the day. In essence the purpose isn’t so much about accuracy, but an inventive reflection of the ephemeral nature of time passing similar to another sand-based timepiece, the hourglass.
