Sketchpad

Sketchpad was a revolutionary program written by Ivan Sutherland in 1963 that helped change the way people interact with computers. Sketchpad is considered to be the ancestor of modern computer aided drafting (*)(CAD) programs as well as an important influence that led to the development of the graphical user interface. Sketchpad used an x-y point plotter display as well as the recently invented light pen. Sketchpad ran on the Lincoln TX-2 computer at MIT.
