Colour, Silent, Video
This is the final 'stand alone' version of a computer generated graphic.
First made on the Atlas SC4020 graph-plotter computer at the Atomic Energy Establishment at Didcot, as a short sequence of black and white film (Your Lips 1 and 2), this film was coloured by filtering on the Co-op printer. The same material was later incorporated as a component of Threshold. (And in the black-and-white version in Reign of the Vampire).
