Mold is an interactive digital petri dish installation that transforms physical interaction into visual growth. Created for exhibition at Imagine RIT 2025, Mold invites users to place and manipulate physical objects on a tabletop surface, which serves as a canvas for a projected digital petri dish. As users move objects around the table, they trigger the spread and evolution of dynamic mold-like visuals, creating a playful, hands-on experience. This tactile interaction turns the tabletop into a living, responsive playground—where science, design, and imagination intersect.
