21:01:03 Digital Mona Lisa, the first ascii art.
Despite remaining little information on its production process the so-called ' Digital Mona Lisa ', continues after almost forty years to generate amazement. Produced in 1965 by H. Philip Peterson of Control Data Corporation, made use of an ingenious system to play different shades. The original painting by Leonardo, in fact, was ideally divided into 100,000 points with the respective brightness values. Subsequently these values ​​had been rendered by pattern of overlapping characters, managing to simulate up to 100 shades of gray. This is probably the first example of ascii art, achieved thanks to one of the first rudimentary scanner of the story, defined as 'flying spot digitizer' which actually may have been the so-called 'Charactron', able to properly analyze the image to play . The fact is that as in the classic contemporary legends, machinery to produce quest'artefatto were destroyed and very few copies of the print are still unknown, including those present at the Computer Museum in Boston and the Computer History Museum of Mountain View. Remain the raw figures superimposed magically recreate the chiaroscuro and the idea of ​​the original canvas.
