Barbara Buckner (1950, Chicago) employed analogue image processing tools such as multi-channel keyers and colorizer, as well as a Z-80 microcomputer and analogue-to-digital / digital-to-analogue frame buffer to produce the video Greece to Jupiter: It’s a Matter of Energy (1982). A combination of several key layers and colorizer channels produced variations in texture, colour and luminosity, as the Z-80 computer digitized and ‘drew’ the video raster over time.  The work suggests a state of transition, a passage through space and time – from the structured forms of Greece – to Jupiter, beyond our terrestrial world.
