My wife and I travelled to The Butler Museum on the campus of Youngstown State University. This was created using one white light (top center) and small, different shaped panels of clear glass attached to the wall at different angles to the light causing a prism effect as the light passes through the glass and reflects on the wall. Some of the light reflects back through other panels creating the different colors. The sign next to this display read; "This art work is part of the Butler's Art Science and Technology tour for families. (STEAM • Science, Technology, Art and Math)"
