In a 1968 demonstration (not the kind you’re thinking of), Doug Engelbart told us what the computer would look like in the 1990s: including windows, word processing, the mouse, and telecommunications systems. Parts of a film of that demo appear in a PBS special called “The Machine That Changed the World.” Stanford is now streaming the entire film in Real Video. (Unfortunately, in a newer version than Streambox can rip.) I hope they release the video as a whole (instead of in segments) in a format that can easily be recorded and shown in classrooms. I always worry about streaming into the classrooms because something inevitably goes wrong. (via BoingBoing).
