White ABS plastic, (FDM) 5"x5"x7.5"tall, 2004.
Two criss-crossing chains displaying the classical catenary shape, but standing up rather than hanging down -- thus defying gravity.
Woven paper strands, 16" tall, 1997.
Klein bottles come in two topologically different kinds: the well-known "sock turned inside out" and the one produced by sweeping a cross section in the shape of a figure-8 around a loop while giving it a twist of 180 degrees; this is a woven model of the latter one.
Print of a computer model, 16"x16", 2009.
A program has been written to
emulate some of the tubular sculptures created by Charles Perry. This print shows a variant
of his sculpture "Solstice," which is based on a (3,2) torus knots. The basic knot, formed by
the thick rail, is straddled with 300 lightly curved ribs.
Paper models, 4"x4"x4" each model, 2009.
A small set of regular maps, all embedded in a genus 5 surface in the form a of a cube frame. in particular, the models are:
(a) map R5.1, consisting of 64 triangles, based on tessellation (3,8)
(b) map R5.1_dual, consisting of 24 octagons, based on tessellation (8,3)
(c) map R5.4, consisting of 24 quadrilaterals, based on tessellation (4,6)
(d) map R5.4_dual, consisting of 16 hexagons, based on tessellation (6,4)

"My professional work in computer graphics and geometric design has also provided a bridge to the world of art. In 1994 I started to collaborate with Brent Collins, a wood sculptor, who has been creating abstract geometrical art since the early 1980s. Our teamwork has resulted in a program called “Sculpture Generator 1” which allows me to explore many more complex ideas inspired by Collins’ work, and to design and execute such geometries with higher precision. Since 1994, I have constructed several computer-aided tools that allow me to explore and expand upon many great inspirations that I have received from several other artists. It also has resulted in many beautiful mathematical models that I have built for my classes at UC Berkeley, often using the latest computer-driven, layered-manufacturing machines. My profession and my hobby interests merge seamlessly when I explore ever new realms of 'Artistic Geometry'."
