Paul Friedlander, a British artist and physicist, creates these pieces light and motion by rapidly rotating a piece of string through white light. The rope, invisible to the human eye while vibrating so quickly, reveals otherwise invisible bands of color.
"I decided to focus on kinetic art: a subject in which I could bring together my divided background and combine my knowledge of physics with my love of light. In 1983, at London's ICA, I exhibited the first sculptures to use chromastrobic light, a discovery I had made the previous year. Chromastrobic light changes color faster than the eye can see, causing the appearance of rapidly moving forms to mutate in the most remarkable ways."
