"Sphidron 01"

Digital print, 90 x 90 cm, 2009.

We found a new kind of spidron, which is made from two perpendicular logarithmic spirals. One of them is flat and the other one is conic. With this surface we can bisect the sphere and make new - smaller spheres. The logarithmic spirals on the surface of the sphere is called loxodrome. Bisecting the sphere on a path of loxodrome makes possible to create smaller spheres.

The problem was to prove that these Sphidrons are developable. While I am quite sure, others are doubting. The surface analysys shows that the Gaussian curvature is close to 0 everywhere, but the differences could be the result of the theory or of the exactness of the software. In spite of this dilemma, I decided to show my result.

In our paper, written with co-authors, Mr. Walt van Ballegooijen and Mr. Paul Gailiunas we - surprisingly - discovered 42 new spacefillers, following the list of Peter Pears, who published them with minimal surfaces. Our versions made the situation a little more difficult, as we broke their symmetry while we spidronised their faces. We present two examples of this research.

As a designer I started to work on Spidrons 30 years ago. In the last 5 years some excellent colleague joined to the project, and we developed a lot of interesting geometrical creatures. I had a chance also to have exhibitions, presentations and publish papers in different media. Our recent results - I think worth to show to the public.
