From Urban Prototype to Heart of the City in 313 Days was just published on Shareable. Pulse of the City is an interactive public art installation that turns pedestrians’ heartbeats into music. The City of Boston recently commissioned it as a public art piece, and in less than a year, George Zisiadis’ project has gone from prototype to permanent, and from coast to coast. It’s an inspiring story showing the power of cities to rapidly experiment and innovate in creating engaging public spaces.
