Ivan Sutherland Sketchpad Demo 1963
Interface Studies
A TV show about Ivan Sutherland's 1963 MIT thesis software Sketchpad, which ran on the TX-2 computer. It shows a light pen drawing, constraints, snapping, scaling and object-style graphics, foundations of GUIs and CAD.
HN returns to it as a striking demonstration that core GUI, CAD and constraint-programming ideas existed in the 1960s.
