"To me the simple act of tying a knot is an adventure in unlimited space. A bit of string affords the dimensional latitude that is unique among the entities. For an uncomplicated strand is a palpable object that, for all practical purposes, possesses one dimension only. If we move a single strand out of the plane, interlacing at will, actual objects of beauty result in what is practically two dimensions; and if we choose to direct our strand out of this plane, another dimension is added which provides an opportunity that is limited only by the scope of our own imagery and the length of a ropemakers coil." | "To me the simple act of tying a knot is an adventure in unlimited space.

Bugnes, sweet French dough fritters are a wonderful way to explore knots, strips, planes, weaves and other forms in action. Stretching the dough and creating the form, then dipping it in boiling oil shows what happens when the form is subjected to a continuous transformation - a raw tea-cup becomes a fried doughnut, for example.

+ | The last hours of Mathematickal Arts were reserved to deeper explore ideas discovered in the first two days, especially ideas that the participants find most applicable in their practice. The participants proceeded to develop their experiments in smaller groups: textile origami, knotted suspensions, | ||
+ | |||
+ | The workshop leaders re-introduced the question of the workshop - whether bringing mathematics and textiles together increases the resilience of both practices. One hypothesis is that by combining the two, a better balance can be found between a heuristic | ||
+ | |||
+ | One of the examples was the experiment with suspending a cube made out of rope. T participants began making the sculpture by intuitively cutting and assembling pieces of rope, which used a lot of material and many knots. After using mathematics to understand the more optimal way of building the cube, much less rope was used and a different knot, that allowed for easy adjustments. This combination of techniques made the suspended cube more adaptive and in a way more resilient. Another example was that applying mathematics to textiles makes the craft of mathematics understandable and applicable to non-experts and therefore more embedded in common understanding. | ||

+ | === Workshop Outcomes === | ||
+ | |||
+ | |||
+ | == Tour de France fish net == | ||
+ | |||
+ | Martaque designed a net based on historical tour de France scores. She mapped out the progress of individual riders and relationship with other riders, using them as netting points. Every point in the net was determined by the position of two riders in the netting. In this way it was possible to tangibly visualise the speed of different riders at various points in the race. Martaque will use the learnings from this experiment to develop a netted artwork using the results of 2011 Tour de France. | ||

+ | |||
+ | == Suspensions == | ||
+ | |||
+ | Fabian Feraux used the suspended cube as a geometrical shape to enhance the suspensions of humans in space. The cube functions as an etherial aquarium, that changes shape as it is tensed by the elevation of the human body into it. He explored how much weight one can put on what angle of the cube, looking at tension on attachment points. He experimented with Japanese bondage, where knots are only made at the beginning of a new rope. After that, he uses only twists to restrict and suspend a body or an object. In Japanese bondage, a strictly codified system, knots are considered offensive and ugly, in addition to the practical consideration that they take too long to untie if something goes wrong. | ||

+ | |||
+ | == Simulation of elastic rope structures == | ||
+ | |||
+ | Miska Knapek made a simulation of flexible structures, using physics of elastic bands. He creates attachment points and uses them as anchors, the program calculates the ideal distance for the elastics and keeps the structures in dynamic balance. Miska was inspired by varying elasticity of rope (hemp to nylon) and used parametric design to simulate the poetry of physical structures inherent in their emergent dynamics. The result was a small prototype of algoritmic graphics generated from varying relationships in a system, examining the properties of physically inspired pseudo/ | ||

+ | |||
+ | == Textile origami == | ||
+ | |||
+ | Cocky, Pieter, Wendy, Stephanie explored different origami patterns in textiles. One of the approaches was to sandwich polyester organza in-between a paper mould using paperclips. The textile and the mould were placed for 1 hr in the high pressure steamer. When the paper is taken away, the folds stay - polyester keeps the memory of the shape. A mix of polyester and metal proved not to be as successful. The pleats created in this way are permanent until the textile is heated to the same temperature. | ||
+ | |||
+ | The group looked at changing scales for origami textiles - using the same technique to design the textile for the body and textile for architecture. The challenge for the future is to see if larger structures can be made out of one material only (e.g. textile, rather than textile and wood). This has proven more challenging, | ||
+ | |||
+ | {{http:// | ||
+ | |||
+ | Wendy, Stephanie and Eugénie explored creating origami patterns by knotting textiles - building a vocabulary of dots, lines, squares, triangles | ||
+ | |||
+ | The group observed the difference in dimensionality between different materials - sown fabric produced 2 1/2 D, fabric and wood can be reversed from 2d to 3d and back again, while steamed organza patterns always stay 3D. | ||
+ | |||
+ | In addition to origami textiles, Wendy and Stephanie created crocheted hyperbolic sausages that they saw as inspirations for folding and origami books, both in paper and in textile. | ||
+ | |||
+ | Eugénie works together with dancers and is interested in making folds that can follow joints. Wendy will joing her from a Dance & Technology angle - thinking about making completely fabric sensors. The origami folds might help creating a third dimension in a fabric that moves on the body of a dancer. They will continue exploring different materials and colours to exaggerate the movement. | ||
+ | |||
+ | == Ascii weaving == | ||
+ | |||
+ | |||
+ | Dave Griffiths created little programs to create patterns that he would weave in textiles. The program starts with a rule and makes a sequence: e.g. when you encounter a yellow yarn, replace it with a sequence green, yellow, yellow, green. While Dave was weaving from command line, the computer was predicting what the pattern would look like in ascii code. The challenge was to see if the real weave matched with the ascii weave. The first prototype was made in plain weave, but adding more rules would help make something approaching a jacquard. | ||

+ | ==== Conclusion: what happens when you bring maths & textiles together? ==== | ||
+ | |||
+ | |||
+ | == A few reactions from participants == | ||
+ | |||
+ | * The combination of textile and mathematics is very relevant - it clarifies some of the more abstract ideas in science and programming | ||
+ | * Learning how to make the turk's head was a revelation | ||
+ | * It was valuable to look at braiding more in detail and understand topological complexity in the real world (e.g.), rather than just abstractions | ||
+ | * Putting the code in textile - creating information inside the weaves, rather than on it. I'm reminded of threads and fibres as communication systems of the ancient Inkas: | ||
+ | * Self referential weaves as educational materials - showing what the rule set was that created them. | ||
+ | * Working with textiles informed me to make different forms in generative graphics | ||
+ | |||
+ | |||
+ | == AHA moments == | ||
+ | |||
+ | * memory shape fabrics | ||
+ | * calculation for the cube suspensions - understanding maths does help! | ||
+ | * understanding that variations are not endless and knowing that it is possible to know them all | ||
+ | * using a combination of fabric and wood for shelters, waterproof textile hinges is genious - Pieter' | ||
+ | * i have more of an understanding about algorithmic design - reducing a method to something quite simple - short circuiting trial and error, finding productive directions more quickly and more clearly | ||
+ | * finding a new way of working - not only trial and error, not only abstractions, | ||
+ | * the saussage machine is a curiosity, it was great figuring out how it works | ||
+ | * 3 dimensionality of knots & hyperbolic planes (crocheting: | ||
+ | * Force is not necessarily useful for hyperbolic crocheting | ||
+ | * This was a workshop with a high fun factor, so many things popped up suddenly and surprisingly | ||
+ | * the workshop made me specialise in being Martaque | ||
+ | * i hear a lot of music here, which is good! | ||
