'Diagonals' is from MA1 "Abstract Originals" Geoff Davis Micro Arts Group 1984. This was the first generative art collection ever publically released.
In these new artworks, the generative art is running on six surfaces of a 3D cube, which rotates in a void, with synthesised music. This combines historical computer art with modern CGI virtual world graphics. Original music is provided by Metavista.
Originally only numbered (1,2,3,4 etc.) we now have human labels: Lightning Strikes Reversed (Diagonals)
Micro Arts software was distributed on data cassette and later Prestel videotex. "Abstract Originals" comprised seven generative artworks, and had a menu for colour control, order, etc.
