Ando Time Red/gray Hourglass By Tadao Ando

This dynamic hourglass by artist Tadao Ando uses simple geometric shapes to create an exceptional sculptural piece. Encased in a prismatic case in clear blown glass are two, bullet-shaped glass bulbs connected by a narrow tube that carries the sand that dynamically interacts with the clear and red bulbs. It is part of a limited edition of 49 pieces per color.
