Work by John Edmark

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.
