Working in software has made me particularly interested in the fetishization of the artist's hand. That is why a drawing machine is a particularly attractive output device. It mediates the gesture of the hand drawn and the machinic world of software which is most often present to us now as the bloodless surface of a screen.
I wrote my own driver software in java to resurrect this antique plotter which until the mid-eighties was a common workhorse of scientific visualization.
While the primary occasion for this ebay purchase was the SoEx Monster Drawing Rally, I have subsequently done quite a few projects using the machine.
