Edo Timmermans' Model.

who lives in the Netherlands,

using pieces that are rectangular solids,

Cherry wood model of my prism dissection of two 5-pointed stars to a {10/4} star.
This stunning model, of a prism dissection that I first conceived of in the mid-1970's, was made possible by Walt Hoppe's
laser-cutting abilities and my determination not to become unglued as I figured out how to pull together a challenging model.
-
Adding mother-of-pearl dots to my cherry wood model of the prism dissection of two 5-pointed stars to a {10/4} star.
Even more stunning!
