This is another Kickstarter project. The Manifold Clock is a wall-mounted clock with a 30″ sweep. The hour and minute hands are joined with a flexible sheet that forms a changing 3-D shape. This “combination of simple mechanics and modern design is based on the mathematical notion of Riemann surfaces, derived from the log(z) function.” Pledge at least $45 to receive a Manifold Clock. Funding has already been exceeded, but there is still time to pledge and receive a clock. The funding period ends February 23 at 5:00 pm EST.
