Handmade spiral clocks by Aspiral. How does it work? The spiral face turns slowly over twelve hours. The red ball rests on the spiral ledge as the spiral that turns it, travels along the ledge to the middle. At the 12th hour it drops through the hold in the middle to begin its journey again at the bottom. You can choose your own design for the background, change the time the balls drops and even the time markings for your own bespoke clock.
