Deep Walls is a 2002 interactive installation created by Scott Snibbe. The exhibit features a screen with a blank 16 square grid projected onto it. When a viewer walks past the screen their shadow is recorded, and the motion of their silhouette is played randomly in one of the small boxes a short time later. The result is an ever changing collage of moving silhouettes and expectations, where each person’s unique movements are set on delay then played amongst others. While evoking the surrealist films that inspired the piece, its unconventional and open design allow for a constant evoltution within an unchanging frame. Because each person can choose persiscely how long they want their recording to last, the piece becomes a group conception of time with movement. In other words, it becomes an artwork of personal 'moments.'
