Within the entrance lobby stands the ColorCoaster, a kinetic sculpture spanning 27 feet (8.2 m), made by the artist George Rhoads.

This undertaking necessitated the closure of Stepping Stones for roughly three months, culminating in a "grand reopening" on November 20, 2010.

This initiative facilitated the expansion of the museum's interior space by approximately 22,000 square feet (2,000 m2), effectively doubling the facility's available indoor area.

The redesign, a brainchild of Beinfield Architecture, not only magnified the museum's physical dimensions but also cultivated a naturally efficient workspace that was aligned with principles of sustainable energy.

Additionally, an internal telescope was incorporated to facilitate the observation of plant and animal life atop the facility's roof.
