Are you among those people who believe that the past should stay in the past? The Delete Clock from designers Li Ke, Pang Sheng Li and Chen Yi Lin kind of forces you to become one of those people by letting you write out all of the day’s appointments right on the clock’s face – and then erasing them once their time has passed.

The surface of the clock is made of the same material used to make whiteboards. You can scribble down tasks for the day, draw little doodles, or just remind yourself of doctor’s appointments and other important events. But the catch is that you only have a limited time to look at these scrawlings, because after the hour hand passes over your marks, they are instantly erased.

The rather low-tech approach works well on this artistic clock. However, you will have to get used to the hour hand being way bigger than the minute hand, something that we think would probably lead to a lot of confusion and maybe even some missed appointments.
