The document describes three temporary interactive exhibit concepts for a Child & Young Adult Cancer Institute. Concept A features a rooftop garden theme with motion tracking technology allowing children to interact with virtual butterflies. It includes five interactive areas at different heights and an iPad station to control a rooftop camera. Concept B replaces motion tracking with traditional activities like a telescope to discover creatures and augmented reality through iPad stations. Concept C features an aquatic theme where motion tracking immerses children in a virtual underwater world interacting with fish. It includes circular portals displaying animated characters that respond to children's movements.
