Sangaku are geometrical problems carved on wooden tablets. They were very popular in Japan during the Edo period (1603-1867).
Sangaku was the theme for the 12-30 project, month of November. I compiled the entire series with additional artworks inspired by the Sangaku tradition in one volume including over 60 illustrations, the original geometry they originated from, along with their mathematical description and possible solution
The book is now available in electronic format on the iBook store, GoogleBook, and Kindle. The individual images, large size print on canvas on SaatchiArt.
“The Quaste quandary”, vol. nº 8 of the Math-Art series, is now available on the iBook store @http://bit.ly/JCDigitalBooks , GoogleBooks @http://bit.ly/JCGBooks . A black&white version is also available on Kindle @http://bit.ly/JCPublishing
This book, as well as vol. nº 7, “The Mathematical Surfer”, features some of the works I produced at the beginning of the 12-30 project, month of January.
“Boy singular surfaces” – Math Art series, vol. 6, is now available on the AppleStore and on GoogleBooks. A black and white version is also available on Amazon-Kindle.
The 12-30 project is entering a new phase – moving images!
4 cinemagraphs I selected for a new project next year. I saved that one for this blog:
An “infinite loop” shower of golden snowflakes for all in 2017!
The 12-30 project will continue with a life of its own this time. I’ll keep posting images as they come – when they are included in real-time exhibitions. The original (large files) will be printed 18×18 or 24×24 on aluminum or linen canvas depending on the venue and the image.
This one (#150 in the project) is part of an exhibit of my work at the JMM conference in Seattle, Jan 6-9.

MathMod & Morenaments. “Night in Russia”. A Chagall-like shape coming out of a double twist Neovius torus. After an original template by A.Taha.
Background: A pmm symmetry. The sixth symmetry consists of two perpendicular reflections It produces a “double mirror” patterns (pmm)
December 25 – 359
MathMod & Morenaments. The dervish surface is an algebraic surface related to the Togliatti quantic. I reworked the parameters with the number 18 – a very significant number in the Sufi culture.
Background: P31m symmetry. This symmetry group is part of a series of tiling based on the p3 tiling used in many ancient cultures.
