Malin Christersson posted this super clever GeoGebra sketch (http://tube.geogebra.org/m/2051073) of shapes of constant width, which got me thinking about these today. This sketch shows one with radial symmetry and odd number of vertices, and a non symmetric one built on three directions. Fun to make & I feel like I understand the geometry a bit better.
