Blooms

Blooms are 3-D printed sculptures designed to animate when spun under a strobe light. Unlike a 3D zoetrope, which animates a sequence of small changes to objects, a bloom animates as a single self-contained sculpture. Here you will find a selection of my bloom sculptures available to buy and print for your personal use and enjoyment.

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

Fibonacci Tiling

A self-similar tiling, in which every piece is a unique size, but all pieces are the same shape. Each piece is added/removed at an angle of ~137.5 degrees from the previous. This angle—known as the Golden Angle—is manifest in natural objects such as pine cones and sunflowers.

Material: laser-cut MDF

Transtower I (Animated)

The transformations in this tower result entirely from rotating the individual layers by the golden angle with respect to their neighboring layers. (Note: this is not CGI; it is a stop-motion animation of laser-cut MDF)

Material: laser-cut MDF

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

Transtower II (Animated)

The transformations in this tower result entirely from rotating the individual layers by the golden angle with respect to their neighboring layers.

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

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

Nested Fibonacci Tower

Stop-motion animation of laser-cut and laminated plywood frames.

A Talk about my Phi-Based Explorations

The plant forms below share the same essential growth process; each new leaf or areole is placed 137.5º – the golden angle – around the center from the previous. Any plant that uses this growth process is a potential candidate for being animated as a bloom.

Nature uses this same growth process in a wide variety of plant forms, including pine cones, and sunflowers. If you count the number of spirals on any of these plants you will find that they are always Fibonacci numbers.

Natural Bloom: Artichoke

Here we see an artichoke spinning while being videotaped at 24 frames-per-second using a very fast shutter speed (1/4000 sec). The rotation speed is chosen to cause the artichoke to rotate 137.5º—the golden angle—each time a frame is captured, thus creating the illusion that the leaves are moving up or down the surface of the artichoke. (The movement is wobbly because the artichoke is not completely symmetrical.)

Cactus #1 (Top View)

For each frame of the animation the cactus is rotated 137.5º—the golden angle—which creates the illusion that the areoles are emerging from the center of the cactus. (The irregularity of the movement is due to the areoles not being perfectly consistent in their placement.)

Cactus #1 (Side View)

For each frame of the animation the cactus is rotated 137.5º—the golden angle—which creates the illusion that the areoles are emerging from the center of the cactus. (The irregularity of the movement is due to the areoles not being perfectly consistent in their placement.)

Cactus #2

Chromataxis 8X13 H89

The spiral mesh consists of 8 spirals in one direction and 13 spirals in the other.

Such a configuration cannot be colored like a checkerboard;  a conflict would arise that forces some identically colored cells to abut.

To get around this problem, the cells have been colored so that that their hues shift according to their angle around the center.

The result is a checkerboard pattern that uses complementary hues to create contrast between cells.

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.
