Camille Utterback's piece, Abundance, uses cameras and animations to tackle the idea of surveillance. Utterback transforms a city block into a virtually animated map. Cameras track city pedestrians and their path is animated an then projected on to a building. Individuals were portrayed in cool colors and when a group of two or more formed the paths would become warm colored.Also, indiviual paths would erase the animation's background where as the path of a group would fill it in. Furthermore, over time, Utterback started to add graphic elements to the animation that would effect the path of the pedistrans. "white lines were added to the projection which align with slats in the building facade. As participants cross these lines, moon-shaped graphics are released and travel in a trajectory opposite the person’s movement. These flickering nodes become active elements of the composition – releasing further bursts of color when another person moves across them" (www.camilleutterback.com).
There is a hue difference between the surveillance camera in London and Utterback's Abundance. The cameras in London act as an eye for the government and for the apparent safety of the people, while abundance helps the give the people of San Jose a feeling of "ownership of a public space" (camilleutterback.com).
