The Manifold Clock Kickstarter project embraces the mathematical concept of Riemann surfaces to create an artsy 3D timepiece that expresses time through shape and movement.

Arithmetic has never been so infuriating. “1+2=3” is a math puzzle game that limits itself to asking players to solve equations that only involve those three numbers, against the clock.
