50 years since Sketchpad demonstration

TUAW notes the 50th anniversary of the first demonstration of Sketchpad, the first computer program with a GUI. Long before the rise of the Xerox and Apple's GUI in the 1970s this was a drawing program developed by Ivan Sutherland for his PhD and is considered the direct ancestor of Computer Aided Design (CAD) systems. Sketchpad is also considered to have pioneered the Graphical User Interface, object orientated programming and human computer interaction (HCI).

In the video below Alan Kay discusses Sketchpad and shows a demonstration.
