Continuing a line of thought from before...
Above is an image describing a project by Natalie Jeremijenko -

When you enter the lot, a colorimeter scans the color of your car and issues a parking ticket assigning your space. Cars are arranged according to color, transforming the mundane act of parking the car into a large public spectacle. The parking lot, a site that might be considered culturally bereft, becomes a display of public participation. It is a project that makes tangible the extent of vehicular obedience.

two good websites to try:
Yale Alumni Magazine article about Jeremijenko titled An Engineer for the Avant-Garde
Walker Art Center piece titled Database Politics and Social Simulations, also about Jeremijenko, which includes the italicized text above.
