“ASCII.LIVE” is a light artwork by ASCII Art Ensemble presented at GLOW Eindhoven 2010 in Eindhoven, Netherlands.
Most people are familiar with ASCII from the list of number combinations that, when combined with the Alt key, produce special characters in word processing programs. Before it became possible to print images, representations were converted into numbers, letters, punctuation, and other symbols.
