Nothing that was written for the computer in the 90s could match an
    installation like Jeffrey Shaw's "Legible City" - neither
    technology-wise, nor conceptually. After all, Shaw had employed a
    Silicon Graphics Crimson computer that was worth several ten thousand
    dollars to achieve the right effects. Only with such a machine, it
    could be suggested to the audience that its own activities were
    synchronized to the movement of the digital image on the screen.{1}
