Called Manifold Clock, the striped sheet is made of Tyvek, and slowly curls and unfurls.
Here's a tiny bit of information from the designers:
The Manifold Clock.
We connected the clock's two hands with a manifold to create a 3D movement.
The time can be read traditionally using the two hands, while a new reading method is created when clock demonstrates an ever-changing form every minute. It is a combination of modern design and simple mechanics.
