A "large-scale urban earthwork and landscape painting in real time and space" dazzles travelers riding the Northeast Rail Corridor in Philadelphia. The pubic art work, psychylustro, by artist Katharina Grosse, realized with Philadelphia Mural Arts is a temporary site-specific installation.

The work was recognized by Americans for the Arts Public Art Network (PAN) Year in Review which annually recognizes outstanding public art projects that represent the most compelling work for the year from across the country.
