See the System Behind Engelbart's Historic Mother of All Demos

On December 9th, 1968 Douglas Engelbart gave his Mother of All Demos, showing for the first time the mouse, hypertext, windowing, outlining, teleconferencing, and more.
Today is the 45th anniversary of this demo. In honor of this the HyperScope team has put together a video showing some NSF-funded work we did in 2006 porting parts of Engelbart's original NLS/Augment system shown in the Mother of All Demos into contemporary web browsers.
