First up is a beautiful animated piece, 12 minutes in length, that quietly, beautifully captures a grandfather sharing a memory with his granddaughter.
Next, this 5 minute animation of ART, illustrating how people walk. Simply gorgeous, it earned Ryan Larkin an Oscar nomination (short animated film) in 1968.
And finally, a 29 minute triumph of film art from 1960 by Roman Kroitor and Colin Low, creating on the screen a vast, awe-inspiring picture of the universe as it would appear to a voyager through space. This film was among the sources used by Stanley Kubrick in his 2001: A Space Odyssey. Realistic animation takes you into far regions of space, beyond the reach of the strongest telescope, past Moon, Sun, and Milky Way into galaxies yet unfathomed.
