Picture of the Day


"Geometron" is a specially-commissioned artwork by John Edmark for the "Geometry Playground" exhibit at the San Francisco Exploratorium. With "Geometron," the viewer looks into a tapered kaleidoscope to see a live video that creates a 120-sided shape and explore many symmetries within the image by moving glowing shapes in the camera’s view.

"Geometry Playground" is a fully interactive exhibition that includes over twenty exhibits and specially commissioned artworks. With "Geometry Playground," visitors use their hands, their bodies and their minds to explore what for most has been only a textbook subject. The exhibition was funded by the National Science Foundation and the Gordon and Betty Moore Foundation.
