Etch Clock Engraves the Time

Meet the Etch Clock: a work of art with a surface made of a transforming thermo elastic membrane that forms digital numbers. They appear to be engraved into the surface. As the time goes by, the surface is wiped every 30 seconds and replaced with the current time.

The app lets you select 12 or 24 hour time format. The display can also be programmed to respond to sound.
