Today’s model is an example of what Tomoko Fuse called “growing polyhedra”. Fuse basically provides a construction kit–designs for triangular double-pyramids and connectors. These components can be put together in any number of ways. I decided to create three layers of hexagons following the crystal structure of graphite–specifically the “ABC” allotrope. This model is quite large, about 8 inches across–and very sturdy too.
