This is the ETCH clock one of the coolest ways to tell time I have seen and you may like it too. Wake up your imagination to a new way of looking at time that reflects how each moment is fleeting and unique. This clockâs surface is made of a transforming thermo elastic membrane that forms digital numbers, which appear to be engraved into the surface. As the time changes, the surface is wiped blank every 30 seconds followed by the updated time. Like it and want it then go HERE to get it.
