This is a really clever clock, you pop it on a wall or whiteboard, add a marker and it marks out time on the wall, I think this would be a fun project to build. From the site – “Are you the sort of person who projects to those around you an affinity for temporal illustrations? If so everlab’s 1 HOUR CIRCLE is just the thing for you. Simply adhere to the wall, or set on a sheet of paper, and the 1 HOUR CIRCLE will be ready to fulfil its obligation.” [via] Link.
