For the past 12 months we have been working with various local artists and tools to explore light in conjunction with a Light Exhibit here at the Science Museum of MN. Some of the materials we explored were LEDs, transparent and reflective recycled materials, conductive tape and thread, and more. For more information or to try some of the activities we had success with visit the Light site. This photo is from Krista Kelley Walsh's workshop in the Managing Light gallery: Magic of Material and Light.
