200 Main Street [an inventory of time and place] is a participatory project built from objects, photographs, ideas, and personal accounts contributed by Los Altos residents about what home means to them. Drawing from original photographs, community contributions, and historical materials from local and regional museums, the project takes the form of a 30-foot-long photographic mural installed on a public wall. Composed to resemble the interior of a home, the mural stretches across the façade at 200 Main Street, Los Altos, California, transforming the site into a shared portrait of place and memory. The project was supported by Arts Los Altos and funded by the Los Altos Rotary Club.
