Engelbart's Violin
You have probably heard of Douglas Engelbart. He is best known as the inventor of the computer mouse - but in fact, this man created just about all of the conceptual underpinnings of what we now think of as the standard human-computer interface. Engelbart presented his ideas to the public in one long demo session on December 9, 1968. This demo is known today, quite appropriately, as 'The Mother of All Demos.'
