Hiya,

    Yes, the first reasonably complete interface was created at Parc.
BUT, the ideas and inventions occured much earlier. An object oriented
direct manipluation drawing system existed in the 60's ! It used a
light pen instead of a mouse, but the ideas were the same. In reality,
you have supported my point. The Star User interface was actually
implemented a few years earlier by David Canfield Smith for his thesis
(in Smalltalk !).
