This is a straightforward shape variant but in this case the shape is the Szilassi Polyhedron.
It has two strange properties.
1. Each face of this polyhedron shares an edge with each other face. The only other shape is a tetrahedron.
2. As a result, it requires seven colours to colour all adjacent faces, providing the lower bound for the seven colour theorem.
