This one was on slashdot more than a week ago, but I just found the time to upload the movie to my webserver. From a historical perspective, this video is amazing. Shot in 1992, it has lots of technology introduced almoast ten years later again with the release of Mac OS X. If you watch the video, you will see mail.app, interface builder, the dock and more.
Amazing.

Original credits go to openstep.se, and here is the slashdot link.
Openstep.se still seems being slashdotted.
