A German word that could mean a tassel or a bushel in English, the Quaste unusual form combines algebra and geometry to provide unexpected, almost surrealistic art forms. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks. It also includes an original media file.

20-illustration portfolio on algebraic curves and work-related equations created in the program SURFER. Mathematical art inspired by the work of Arthur Cayley, Wolf Barth, and other exceptional mathematical shapes. The portfolio is part of a much larger project on mathematical art, titled “The 12-30 project” completed in 2015 and available in printed format on Amazon.com. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks.

20-illustration portfolio inspired by Boy surfaces. Mathematical art inspired by the work of Werner Boy who discovered how to turn a sphere inside out in a three-dimensional space by creating a 3-fold rotational symmetry. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks. It also includes an original media file.

Cantor set revisited according to the Sierpinski square-recursion fractal. 20 mathematical visualizations enriched by mixing the resulting geometry with various optical illusions. The gallery portfolio is followed by a detailed report on the technical process and the optical illusions sources. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks. It also includes an original media file.

20-illustration portfolio and original mathematical models from B. Rieman family of minimal surfaces on Minoan culture geometrical background. Riemann’s work on the properties of surfaces in higher dimensional space was based on intuitive reasoning. Cretan, Minoan art is rich in symbols and abstract geometries. Both complement each other unexpectedly, yet often in a mysterious and poetic way. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks.

20 illustrations inspired by the work of Robert Dickau on mathematical figures and focusing on the Bell numbers, 5- and 15-partition schemes. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks. It also includes an original media file.

Series of 20 illustrations inspired by the geometry of a conformal map. Widely used in Physics and engineering, conformal mapping also makes for an unusual and appealing art-form. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks. It also includes an original media file.

Series of 20 B&W illustrations inspired by the geometry of a hyperbola. This particular series was inspired by Bernie Freidin work on hyperbolic tiling. The 4-color version is available on the Apple store @http://bit.ly/JCDigitalBooks and on GooglePlay @http://bit.ly/JCGBooks. It also includes an original media file

A 1 year long, 1 image a day - visual marathon, inspired by mathematics and geometry. Twelve mathematical visualization programs, one program a month, one image a day in each program - January 1st - Dec 31st, 2015. 365 illustrations, figures descriptive and formulae. Rev 2 include additional images not featured in version 1.

Visual diary. Progression of a design over an entire year, one image per day. Each image is both a self-standing artwork and a progression from the previous day's image. Complemented with written notes taken during the project, software used and technical info on the image making process.

52 grains of sand - Geometry of Nature. A visual journey through the geometry of 52 minerals, one mineral a week, January 1 - December 31. A blend of Science and Art imagery. 365 illustrations plus text.

Artistic interpretation of the 32 crystallographic point groups system. Mathematics helped applied sciences define the nature of crystal. Crystallography uses symmetry to outline the singularity of a diamond, a ruby, a sapphire and most gems often defined in terms of beauty, balance, and harmony. Can art use information based on scientific observation meet the challenge of beauty and relevance?

The second part of a visual essay on Sangaku. A blend of modern art and universal geometry inspired by a unique Japanese tradition
