Ingenivm Nobis Ipsa Pvella Fecit (1974)

(Formerly titled "VERNAL EQUINOX," 5 minute excerpt of Part 1 on the Criterion disc) "...Frampton explores human movement in relation to the film frame. A woman is filmed against a black background with intermittently superimposed frame lines in a motion analysis which alludes to Muybridge."–program note, Whitney Museum of American Art.
