The Main Street Prototyping Festival will feature 20 temporary prototypes (created by artists, architects, designers, students, makers, urban planners and others) that activate public space and engage the community toward enhancing connectivity and vibrancy in downtown Mesa. Prototypes include concepts for gathering places, virtual reality experiences, structures that offer space for interaction, performances, places to play and share in art making, and ways for passersby to offer feedback about their community. Free.
