In 1987, kaleidoscope artist Thea Marshall, working with the Willamette Science and Technology Center, a science museum located in the Eugene, Oregon, designed and constructed a 1,000 square foot traveling mathematics and science exhibition, "Kaleidoscopes: Reflections of Science and Art." With funding from the National Science Foundation, and circulated under the auspices of the Smithsonian Institution Traveling Exhibition Service (SITES), the exhibition appeared in 15 science museums over a three year period, reaching more than one million visitors in the United States and Canada. Interactive exhibit modules enabled visitors to better understand and appreciate how kaleidoscopes function.
