Grass Roots Square was created by Korean-American artist Do Ho Suh. 

The unassuming square sits just outside an office block. There, thousands of mini bronze figurines either take the place of paving stones (which have been removed) or are under them. It gives off the illusion that some of the stones are being lifted from the sidewalk. The installation is meant to embody a grassroots movement. With the varying ages, sex, and ethnicity of the figures, it also represents a united mass.
