Poem Field is a series of eight computer-animated films made by Stan VanDerBeek with programmer Ken Knowlton at Bell Labs, beginning in the mid-1960s. The images were generated in Knowlton's BEFLIX language on an IBM 7094.
VanDerBeek and Knowlton’s Poem Field videos and those early films that Lillian made are just extraordinary works of generative art.
