Sasa clock by Thorunn Arnadottir

Beautiful and poetic conceptual design by Thorunn Arnadottir. From the designer's website: "The time is read from the color coded necklace. Each bead represents a 5 minute increment. As the wheel turns, every 5 minutes a bead drops down the cord. Orange beads represent hours, gold and silver beads represent noon and midnight."........"To "stop time", remove the beads and wear them proudly, as a statement that you are in control of your own minutes.
The clock is manufactured and sold by Daniel Estes Designs
