Ptoing had a picture that errored out on a real c64 creating random garbage outputs, I chose one and worked over it.
"As is commonly percieved, the relationship between a human operator and a machine is such that the machine is a tool, an instrument of the composers desires. Implicit in this, and generally unquestioned until recently, is the sovereignty of the composer. What is now becoming clear is that the composer is as much a tool as the tool itself, or even a tool for the machine to manifest its desires. I do not mean this in the sense that machines are in possesion of a mind capable of subtly directing human behaviour, but in the sense that the attributes of the machine are just as prominent an influence in the resulting artefact as the user is; through his work, a human operator brings as much about the machine to light as he does about himself." - Tom Jenkinson
This explains the theoretical framework of what was attempted. This isn't any sort of abstract art.
