The Johnson solids are 92 ingenious convex polyhedra discovered by Professor Norman Johnson in 1966 that expand the five traditional Platonic solids as a landscape of convex forms with sometimes wonderfully exotic names, such as a Gyroelongated pentagonal pyramid, an Elongated pentagonal gyrocupolarotunda (see https://mathworld.wolfram.com/JohnsonSolid.html). They are represented by both origami layouts as well as their 3D forms. I spent a period utterly absorbed in the geometry of these lovely pieces of nature. But in the end, I realized that I preferred less geometric forms.
