The world’s largest participatory art project, Inside Out, has hit Vancouver. Skyview High School, to be exact.

Skyview seniors Marta Alcazar, Rubyna Ali and Shelby Sherman, working with teacher Jenna Biggs, spent months taking pictures of their classmates and staff members. The result is Vancouver Inside Out—a series of 40 large black-and-white photos that will be displayed on the school’s exterior along NW 139th Street until after graduation on June 12.

Inside Out began in Paris, France, in 2011 as a way for people to convey stories, identities and causes in a public forum. Similarly, the Skyview portraits demonstrate the subjects’ personality and school-wide unity. The three seniors spent months identifying standout students from a variety of cultures and abilities.

The photos were printed by Inside Out on durable, biodegradable paper and adhered with an organic wheat paste. Afterward, they will be removed by a pressure washer.
