Henry Segerman is a postdoctoral mathematician. His mathematical research is in 3 dimensional geometry and topology, and concepts from those areas often appear in his work. Other artistic interests involve procedural generation, self reference, ambigrams and puzzles.

Sphere Autologlyph
Sphere Autologlyph
10.4 cm x 10.4 cm x 10.4 cm
PA 2200 Plastic, Selective-Laser-Sintered
2009

The surface of this self-referential sphere is tessellated with 20 copies of the word "SPHERE". The design was sketched on paper (at Bridges 2009), then a single copy of the word recreated in Adobe
Illustrator and imported into Rhinoceros 3D. The flat design was then projected onto a sphere, modified to account for the curvature of the sphere, then copied to form the tessellation. Finally, pipes were constructed around the curves, converted to a mesh and then the mesh sent to Shapeways.com for 3D printing.

Torus Autologlyph

10.1 cm x 10.1 cm x 3.5 cm
PA 2200 Plastic, Selective-Laser-Sintered
2009

The surface of this self-referential torus is tessellated with 16 copies of the word "TORUS". The design was originally intended for display on a torus with a flat Euclidean metric. However, that design, made from curves in Adobe Illustrator and imported into Rhinoceros 3D, was projected onto the usual embedding of a torus in 3 dimensional space, using Rhinoceros 3D's "Sporph" command. Finally, pipes were constructed around the curves, converted to a mesh and then the mesh sent to Shapeways.com for 3D printing.
