Zamet Center

The Zamet Center in Rijeka, Croatia by 3LHD architects. A beautiful application of the cairo tiling. Thanks to Calgar for advising me of this project.

Homotopy of Boy and Roman Surface

In topology, a smooth deformation from one surface in an other is called homotopy. The parameterization of this homotopy can be found on wolfram's page.

The grasshopper definition, download here.

This figures from Werner Boy's paper (1903) show the topological construction of the boy surface.

A proposal for a pavillion by Christophe Delsart and Yvan Ngnodjom based on the boy surface for the ARPAM project.

Boy Surface

The Boy Surface has been found 1901 by Werner Boy. One obtains a topologicaly equivalent surface by attaching a Möbius strip to a disk along its boundary. Like the Möbius strip this surface is nonorientable.

This beautiful parameterization, based on complex numbers, was discovered in the late 1980s by Rob Kusner and Robert Bryant. In this post the boy surface has already been mentioned on eat-a-bug.
