Logan, Utah – Particle Falls, Andrea Polli and Chuck Varga’s environmental artwork, uses real-time visualization to expose air quality issues that are often ignored. It consists of a waterfall of blue light projected onto a building; the light turns fiery orange or red when there’s particulate pollution in the air. On view at Utah State University through April, Particle Falls has been shown in a number of other cities in the past few years, including San Jose, Philadelphia, Detroit, and Pittsburgh. The animation in this link is from the original San Jose showing in 2010 is designed for cell phone viewing. The video below shows Particle Falls in San Jose. The work was brought to the Utah by ARTsySTEM, an interdisciplinary initiative between the arts and sciences at the university.
