This work was made by Lillian Shwartz in the 1970’s, who was a big leader in creating computer-mediated artwork. When I saw this display, I thought the colors blocks were really cool and was wondering how they were generated in a way that was both methodically changing and aesthetically working together. Schwartz made these at AT&T Bell Labratories, at a time when this type of computer-generated artwork with color had not really been seen before. For one of these, called Enigma, she had to use a sequence output program called EXPLOR, which divided the screen into grids. In one part of the film, it alternates back to black and white to create a strobe effect. In the second part, it explores interaction between chromatic colors. The program randomly selected the areas/shapes, and this random function intrigued Schwartz.
