Continue Time is a concept clock by Sander Mulder, where each of the three clock hands are connected end-to-end and rotate around each other (for example, the top photo shows the clock at 1:43:03, the lower photo at 3:38:30).
To see this idea in motion, Hand in Hand Clock is a similar concept by Stockholm designer Johan Bisse Mattsson, who offers his work in digital/screensaver form.
