Jupiter embroidery - done! My own design, loosely based on a series of photos by NASA showing the Great Red Spot devouring nearby little spots :-) Chain stitch in cotton, silk and specialty threads.
Cummulus (Ciro Najle) -
Najle says crochet is the perfect medium for representing fractal structures because its surfaces can be subdivided again and again by varying the length of neighbouring crochet lines. This can create the necessary curvature for cumulus clouds, in much the same way that crochet has been used to represent the hyperbolic surfaces of corals.
Translating this complexity into cloud art involved a serious amount of mathematics. The sculpture comprises crocheted squares, each of which has an individual pattern modelled by Najle, who generated 1664 different diagrams pinpointing the intersections of the woollen strands, the crochet knots that are key to its structure. It took a team of nearly 40 crochet craftswomen in Merlo, Buenos Aires, Argentina just over a week to make the panels, which were then sewn together into larger sections to form the glorious whole.
