Thanks to all who stopped by Abstraction at Work yesterday. As planned, the site-specific performance/installation took place at an abandoned lot on Washington Boulevard between Landmark and National from 9 am. to 6pm. Cars honked. Artists and puzzled pedestrians --including a share of canines-- inquired about the work in progress, activating lines of communication. Others had their eyes on automatic pilot or in sync with their Ipods. Artistic labor was undifferentiated from street marking, becoming visible only after a few hours, as abandoned pavement lines found themselves in colorful company.
