Manfred Schroeder: Prime Spectrum, 1968
In terms of effective complexity, I think this piece combines the order of using same sized, uniformed, black and white pixel-like blocks formed in sixteen squares, and randomness of arranging the color of blocks in certain ways. Also it appears that the tendency of accumulated white blocks are diagonal with concentrations in certain areas, and the fact that the whole photo is symmetric is also a representation of order.
The problem of authorship is really interesting to me. I feel like for digital generative art, when computers started to be the execution or tool, it also became a bigger part of the process of making art. The line starts to blur when both the artist and the computer are working as a team together, since the result would not be the same without the input and response from either sides. In my opinion the computer is more than just a tool when creating generative art, and the computer and artist should be partners, since they are entitled to part of the creation and this certain part alone.
