deWith 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

bartnigHorst 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.

Hommage à Nash: Triangle 9

triangle-9At 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

NeesSchotterThe 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

ExplSchwQuadratAt 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.

schmetterlingHommage à Sonderegger: Butterfly

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.
