The Museum of Science and Industry desired a new permanent exhibit at the north balcony and adjacent spaces.   The exhibit was designed for each participant to learn about their personnel human biology.  To accommodate the new exhibit, the north end of the balcony was extended approximately twenty feet requiring significant structural changes.  A new glass guardrail was installed to differentiate the balcony extension from the original historic construction.    The design featured floating elements which appeared to defy gravity.   A custom LED light fixture was designed to provide a glowing band of colors at the edges of the floating elements.
