If you focus on just one colour at a time, you can see that each colour is a triangular pyramid, for a total of 5 intersecting pyramids.
This is a stellated polyhedron that my mathematician father and I made from scratch when I was about 12. We used only a geometry set, my father's complicated calculations, mayfair cover stock, glue and some tempera paints. And some dental floss to hang it from the kitchen ceiling, where it and 2 others hung for over a decade. "Stellated polyhedron" just translates as "many-sided shape with star-like protrusions" (rather than the geometric solids that are faceted rather than spiky). My friend Doug calls them platonic solids rather than polyhedra, and that is the sort of nerdy conversation that goes on around here.
To make all these models, my father consulted the excellent vintage text "Mathematical Models, 2nd Edn" by H. M. Cundy and A.P. Rollett, Oxford University Press, 1951. You can usually find used copies of it on Abebooks.
For more information, read the description for the whole set.

Stellated polyhedra in our studio with vintage chairs, ceramics and a hand-appliqued pillow (vintage print appliqued onto Knoll upholstery fabric). The polyhedra were made by my father, Alan Brown and I, when I was 11 or 12.
