Transforming a Tetrahedron into a Chestahedron

The chestahedron was discovered by Frank Chester, an American artist and geometrician. It has seven faces of equal size but not of equal shape; therefore it is not a Platonic solid. Four of the faces are equilateral triangles and three are kites that evolve in the transformation process.[more]
In this Demonstration you can control the transformation and rotate the solid. Three views are provided: (1) the tetrahedron without and (2) with the outer tetrahedron and (3) the chestahedron.[less]
