A bilunabirotunda, named by Norman Johnson [1], is a convex polyhedron with regular faces that is not uniform (i.e. not a Platonic or Archimedean solid, prism or antiprism). This Demonstration shows the folding of a bilunabirotunda's net. The net is a generalization of Dürer's partial net. In the graphic, the viewpoint zooms in as the figure closes.
