Mona By The Numbers
Probably the earliest example of computer-generated text art, put together in 1964 by H. Philip Peterson:
In 1964, H. Philip Peterson of Control Data Corporation (CDC) used a CDC 3200 computer and a “flying-spot” scanner to create a digital representation of the Mona Lisa. The image contained 100,000 pixels that were plotted using numerals, sometimes overprinted, to approximate the required density and took 14 hours to complete.
Similar digital images of popular art, cartoon characters, and even nudes adorned the walls of corporate offices, labs, and computer centers throughout the 1960s.
