Generative visual art by Jonathan McCabe:

“The Method goes something like this. Imagine a square sheet of paper, and mark a dot somewhere on it and record its position. Fold the paper along a random axis, and watch where the dot ends up, recording this position. Repeat this thirty-two times. Use a weighted average of that list of points to determine the colour (or at least hue and brightness) of that original point. Now repeat, using the same folds, for as many points on the square as you like (say, several million). What I love about this is that despite the intensely tactile quality of the surfaces, these images have no “thing” to them: they’re visualisations of transformations of space – traces of topological history. This generative technique has lots of neat features. It’s resolution-independent (you can sample as many points as you like), the procedure is simple and compact (32 folds) and because it’s a sequence, it’s richly connected with image structure: the first fold is the most significant in controlling macro-structure, and the last fold influences the smallest level of detail. McCabe uses genetic algorithms to search and “optimise” the space of possible fold sequences / images.”[this quote relates to McCabe’s exhibition The Origami Butterfly Method, not these displayed artworks]
