I'm an eclectic origami designer: I like to create modular polyhedra and stars but also animals, boxes, and multi-piece tessellations. Since I discovered origami I liked the possibilities it gave me to translate in a physical form lots of concepts and objects of mathematics. I work as a guide in a math museum and paper-folding is a very useful tool to show the beauty and fun of geometry (or arithmetics or algebra) to kids of all ages.
This is a modular origami made from 12 units. I folded each unit
from an uncut regular pentagon, and I assembled them without glue.
The finished model has the shape of a Small
dodecahemidodecahedron, a nonconvex uniform polyhedron. The
folding sequence is very simple and it leaves the faces (12
pentagons and 10 decagons) clean. Instead, the assembly can be a
little tricky due to the odd nature of the pentagon. Since at a
first look it resembles an Icosidodecahedron (they share the same
convex hull) and it was made with a Japanese art I named this work
Icosidō (dō = the way of).
With the same principle applied to a square sheet it's possible to
build, with 30 units, a model close to a faceted
Rombicosidodecahedron
