Cover of "Computers And Automation And People" magazine, January, 1973. I was able to recreate the image based on a small description (in page 5): "Front Cover Picture: The front cover drawing, called "Phropase", was produced by an Algol 60 program, drawing straight lines ax + by + c = 0, where a, b and c were "stepped arithmetically in nested loops". The computer used was an ICL 1904A, driving a Calcomp 1934/6 plotter. The programmer artist is Nihan Lloyd-Thurston.

worth noting that with any of the dark-mode dwitter profiles, many dweets appear with a white band at the bottom :P this has bitten me before
