Weir Shapes

From the series "Look Kool"

Hexa-flexa-WHAT-agon?! Today we get to play with the world's kookiest, craziest 3D shapes! We’ll find out how some bumpy looking shapes can deliver a smooth ride; our challengers will try to feel their way to victory, and Hamza will invent his very own shape: the bloopezoid! Shapes in the polyhedron group such as cubes, prisms and pyramids have surfaces that are all flat; but non-polyhedron shapes such as the torus, the hperboloid, and the reauleaux triangle have at least one surface that is not flat. Shapes of constant width behave just like circles or spheres and a gomboc always lands right side up. Weird!
