This Hyperbolic Surface sculpture was constructed out of paper in 2001 with Christopher W. Tyler.

Connecting regular 7-sided polygons (heptagons) together to form a surface results in a geometry that cannot exist in flat (Euclidean) space. Instead, it creates a regular tiling of the hyperbolic plane. Specifically, the arrangement where three heptagons meet at each vertex forms the heptagonal tiling with Schläfli symbol.

The piece is about 4-feet wide.
