We describe the realization of two interactive, mixed-reality installations arising from a partnership of K-12, university, and museum participants. Our goal was to apply emerging technologies to produce an innovative, hands-on arts learning experience within a conventional art museum. Suspended Animation, a Reflection on Calder is a mixed-reality installation created in response to a sculpture by Alexander Calder. Another Rack for Peto was created in response to a painting by John Frederick Peto. Both installations express formal aspects of the original artworks, and allow visitors to explore specific conceptual themes through their interactions. The project culminated in a six-month exhibition where the original artworks were presented alongside these new installations. We present data that the installations were well received by an audience of 25,000 visitors.
