Helicone

An Interactive Kinetic Sculpture. Through the use of internal stops, each arm is constrained to rotate a maximum of 68.75° (1/2 the Golden Angle) relative to its neighboring layer.

The Helicone is available at a number of retail venues including the MoMA Design store and Guggenheim Museum store in New York City. It may be found Online at momastore.org, and Amazon.com.

The Helicone is featured in an article in the New York Times.

Materials: laser-cut plywood, brass, beechwood

Lollipopter

An Interactive Kinetic Sculpture.

The Lollipopter is a multicolored, plastic version of the Helicone.

The Lollipopter is available at a number of retail venues. It may also be found Online at Amazon.com.

Materials: polypropylene, stainless steel, ABS

Patturn

HyperCycles Drawing Tool

HyperCycles Geometric Drawing Tool is based on the Spirograph toy. HyperCycles is essentially a Spirograph inside a Spirograph. This configuration results in an additional periodicity, which allows for the creation of more complex curves, and less regular drawings.

HyperCycles is available for purchase at the National Museum of Mathematics’ online store.

Nautilus Column

Through the use of internal stops, each layer in this tower is constrained to rotate a maximum of 15° relative to its neighboring layer.

Material: laser-cut MDF

Transcolumn

Through the use of internal stops, each layer in this tower is constrained to rotate a maximum of 137.5° (the Golden Angle) relative to its neighboring layer.

Material: laser-cut plywood

Transtower II (Manual)

Through the use of internal stops, each layer in this tower is constrained to rotate a maximum of 137.5° (the Golden Angle) relative to its neighboring layer.

Material: laser-cut plywood

Incremental Transtower

The transformations in this tower result from Incremental Drift, wherein each layer rotates slightly faster than the layer beneath it. There are 32 layers in this tower, so the top layer must make 32 complete revolutions before the tower returns to the same state.

Internal mechanism designed and fabricated by Paul Stepahin.

Material: laser-cut plywood

Periodically Transforming Sculpture (Proposal)

The Periodically Transforming Sculpture is a work I would like to see be brought to life.

The direction I have chosen with this sculpture is a celebration of nature’s diverse strategies for the placement of leaves around a stem, known in botany as Phyllotaxis. By employing many individually controllable pairs of rotating arms around a central column, a nearly endless variety of configurations may be produced.

Interested? Feel free to contact me.

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.
