The video, divided here into thirty-five(!) RealAudio segments, is not only historically significant, but it’s also uncommonly beautiful. Englebart, with the calm, assured manner of a kindly uncle, narrated the audience through a series of quietly innovative computer tasks, and it feels like listening in on a relaxation therapy session. The image is cropped in such a way that his head is disembodied like some sort of ghost, and it is often superimposed on top of the screen itself, achieving an effect that is bizarrely evocative of postmodern painting.
