It is a custom at many high schools for each graduating class to give a gift to the school. Seniors typically raise money to buy a bench, a tree, or perhaps to create a scholarship fund. The class gift tradition at the Rudolf Steiner School of Ann Arbor High School is different—it is built right into the curriculum. Almost every year since the school graduated its first class in 2000, the seniors, under the direction of the school’s art teachers, Elena Efimova, Riccardo Capraro, and Nataliya Pryzant, create a large mosaic that is then permanently mounted at the school’s Pontiac Trail campus building. The resulting mosaics are remarkable in a number of ways and fulfill several functions. First, there’s their size. Last year’s piece, for example, is eight feet by eight feet, which in square footage doesn’t even qualify it into the top three of the fourteen mosaics that students have created over the years.
