Mr. Horibe's story

Yesterday, Mr. Horibe informed me with email that he made the first regular polyhedron with duralumin tubes around 1975. After that he was busy on teaching and nothing was done for a while.

However, around 1995, he made the first bead model of dodecahedron which was consisting of 30 balls based on the problem described in the famous math book (Sangaku book, 算法助術) from the Edo period (江戶時代) of Japan. Since then, he started to make many different kinds of mathematical beadworks alone for about 17 years until we met last week. He said he will keep on making more bead models.
