With the DAG I would like to document some results of my recoding & remixing of early Computer art and other art directions (done with Snap!, a visual programming environment). They are tribute to the respective representatives of the early computer art. The collection will be continually completed; it’s worth to visit again …
Hommage à Bartnig: Development to the Square
Horst Bartnig is a representative of Concrete Art, who used the computer to create series and variations. A typical example is Development to the Square (original white on black), in which lines in a tabular arrangement multiplied and produce a compression effect.
The creation of this and comparable images is relatively simple with nested loops.
Roger Coqart is the artistic name of the Belgian photographer and computer artist Roger Kockaerts. The computer helped him to „strive for objectivity in the design process of geometric abstraction“. One focus was the systematic investigation of grid structures from squares, to which he superimposed further structures. He obtained these structures by bisecting and diagonal lines. The squares generated in this way were then combined into a square matrix.
For the recoding the procedures to draw the different lines are put into a list („procedures as data“) which allows their easy use in different structures.
Hommage à Csuri: Feeding Time
Also figurative graphics have found entry into the computer art. The source images are to be created manually, but can be easily varied in size and orientation. At Charles Csuri and James Shaffer, the origin is the drawing of a fly. This is then distributed in concentric rings around the image center with random deviations. This arrangement almost calls for an animation to be developed in which the flying flock moves continuously across the stage.
Hommage à CTG: Bird of Passage
Behind the Computer Technique Group(CTG) was a Japanese group of art and technology students whose theoretical work has appeared in journals and whose works have been shown in galleries and exhibitions worldwide. In several pictures – which belong to the Kassikern of the early computer art – they showed possibilities, how pictures can be transformed into each other. Famous is on the one hand Return to the Square, in which a larger square is first transformed by reduction and distortion in a human profile and this then back into a smaller square. The same principle applies to Running Cola is Africa, in which the outline of a runner is transferred to a Coke bottle and then into a silhouette of Africa. The transformation processes are shown in the static overlay of numerous intermediate stages.
Based on this is my Recoding, which I call Migrant Bird Germany Africa, because it contains the three target graphics migrant bird, and outlines of Germany and Africa. Obviously I also made a real animation (morphing) out of it.
Hommage à Nake: Geradenscharen
The Frieder Nake series of Geradenscharen is one of the most impressive examples of early computer art. Even if we can comprehend the development of the images algorithmically and can recode them, they are characterized by always surprising constellations, which are characterized by their own dynamics.
The generation of the images is interesting from the point of view of programming them, because, starting from an (invisible) leading line, further straight lines are drawn at random locations with a random slope. The location, slope and their length is made dependent on the preceding straight line.
Hommage à Nash: Triangle 9
At the ASCII art, images are created with the character set of typewriters or printers. The ASCII character set used for this is globally standardized. Particularly suitable for this are non-proportional fonts, that is those in which all the letters are equally wide (such as Courier, originally developed for electric typewriters). Printers have also been used in computer art. An example is the picture Triangle 9 (in Franke, 1971, p. 25) of Katherine Nash (1910 – 1982).
This and similar works could of course be reconstructed true to the original sytle with electric typewriters or line printers. Since it is mainly about the graphic structure, I created the triangles with an external text editor and then Imported them as costumes in Snap! and then positioned and orientated them as necessary.
Hommage à Nees: Gravel
The collection is opened with the picture Gravel. On the one hand, it is one of the most famous images of computer art at all, which is reproduced in many publications. It comes from one of the pioneers of computer art, Georg Nees, who incidentally, as one of the very few, has documented the algorithm. It was the first piece of computer art I had ever dealt with – at first without knowing it was a work of art by Nees.
For me, it was the result of a first independent implementation 1989 with the Logo turtle graphic, based of a picture without title in a programming book. Only now – 25 years later – did I come across his dissertation, while working on early computer art. In doing so, I have been surprised to find that the image Gravel has been realized in quite different ways. I have created the image recursively, while Nees has used simple repetition loops. So different paths have led to the same result.
Hommage à Nees: The Explosion of the Black square
At the beginning of the 20th century Kasimir Malewitsch created an icon of abstract modernity with his image The Black Square. In his paper Suprematism – the non-representational world, he formulates the transition to a free „lawless“ art. Some also speak of a zero point of art.
Georg Nees takes up this picture and leads over in an image series from the single square to many squares. The series fits the title of a symposium of the Gesellschaft für Kunst und Gestaltung (Bonn, 1989): The Explosion of the Black Square. The creation of this image series is also possible simply with nested loops.
This graphic is a recoding of the picture Schmetterling by Bruno Sonderegger (to be found in Franke, H.W. (1971): Computergraphik – Computerkunst, S. 16. München: Bruckmann). The figure was originally developed as a test pattern for a plotter CORAGRAPH. This development as a result of technical developments and their test is typical for numerous examples of early computer art.
The image is composed of four similar line patterns (from right to left and vice versa, as well as upwards and downwards). Due to the superposition of the beam bundles, a moiré effect occurs.
