Roll-Up Spiral

This logarithmic spiral is furled and unfurled by pulling and releasing a string that passes through the inner radius of each section.

Materials: laser-cut plywood, nails, string

Nesting Frames Spiral Tiling

All of these frames were cut from a single piece of wood. They are similar, and logarithmically scaled. Their shape was designed to allow them to be combined to form a spiral tiling.

Material: laser-cut plywood

Folding Spiral

This folding spiral exhibits a surprising behavior when held aloft: the spiral rises up, seemingly defying gravity.

Materials: laser-cut plywood, cloth, glue

Curling Spiral (Outer Spine)

Changing the angle between the two sides of this spiral causes it to furl or unfurl.

Materials: laser-cut plywood, cloth, glue

Curling Spiral (Inner Spine)

Changing the angle between the two sides of this spiral causes it to furl or unfurl.

Materials: laser-cut plywood, cloth, glue

Combined Curling Spirals

Changing the angle between the two sides of these combined spirals cause them to furl or unfurl.

Materials: laser-cut plywood, cloth, glue

Golden Angle

Work based on the Golden Angle, including 'Blooms', 3-D printed sculptures designed to animate when spun under a strobe light.

Spirals

Work with spirals, including the 'Folding Spiral', which exhibits a surprising behavior when held aloft: the spiral rises up, seemingly defying gravity.

Rotating

Works that rotate, including the 'Helicone', an interactive kinetic sculpture that instantly transforms between a helix and a pine cone with a simple, quick twist of the wrist.

Nesting

Among the works, enjoy the 'Nested Fibonacci Tower' where nested frames are rotated by 137.5º (the golden angle) relative to each other, causing them to stack on top of each other.

Air and Water

Works using air & water. Among other installations you'll find the Geyser Wall, where ping-pong balls frolic among 12 geysers via Bernoulli's principle.

Miscellanea

Miscellaneous works, from a puzzle that is a torture device for a perfectionist, to a four-legged chair that is a study in cooperation and interdependence.

Rough Sketches

Quick prototypes, from the 'Geyser Ball Straw'--a Proof-of-concept for a drinking straw toy--to the 'Star Spiral Cone', where twisting the spiral slightly causes the layers to overlap and form a cone.

Space Packings

These works use modular elements arranged in a periodic fashion to explore the fundamental structure of space.

Products

Products and inventions from earlier years. You might be able to find some of them second-hand.
