This week I experimented with a new Processing script that makes a generative piece inspired by Peter Struycken’s Komputerstrukturen 1. I’ve published the code to generate a piece like this below.

int a = 10;

int w = 7*a, h = 7*a; // inch by inch

fill(#0C0000); // Dark Crystal
for (int x = 0; x < width; x += w) {
 // threshold based on a gaussian function (bell curve) that gives
 // a number between 1 in the middle of the screen and 0 at the left
 // and right edges. the 8.0 adjusts the width of the bell, i.e.
 // how quickly the value drops to 0 as you move towards the edges of
 // the screen.
 float threshold = exp(-4.0 * sq((x / width)));
 for (int y = 0; y < height; y += h) {
 // generate a random number between 0 and 1 and compare it to the
 // threshold. if it's less than the threshold, draw a small square.
 if (random(1) < threshold) rect(x, y, w, h); 

// generate a unique filename for each generation based on datestamp
save("Looming"+nf(month(), 2)+"-"+nf(day(), 2)+"-"+year()+" at "+nf(hour(), 2)+"."+nf(minute(), 2)+"."+nf(second(), 2)+"s"+".png");

At this point my goal is to create an original script that will be woven as a jacquard textile and displayed as a 48″ x 36″ tapestry.

I spent this week researching procedural artists that use computing, and notable weavers/textile artists from the Bahuas School.

I came across contemporary artist, Jeff Donaldson, the founder of Glitch Haus textiles. I do enjoy some of his weaves, but I am a little more interested in another project, his “prepared Nintendo” pieces. These are hacked NES video game consoles that are used to generate glitch art. The idea reminds me a bit of composer John Cage’s “Prepared Piano” works in spirit.

I also discovered Peter Struycken and his “Komputerstrukturen” series which are prints executed by computer programs. I really enjoy these, but I am still trying to figure out why exactly.

Next I dove into the amazing work of the Bauhaus textiles & fiber arts group. Two artists that I want to highlight are Gunta Stölzl and Anni Albers.

Stölzl was the Bauhaus’ only female master and her work is thought to exemplify the distinctive style of Bauhaus textiles. Below is an amazing one of her wall hangings titled, 5 Choirs.

Anni Albers was a Bauhaus student of Stölzl and is credited as an artist who elevated textiles from merely a craft to an art form.

I tinkered further with my Processing script, and below is my tribute to Anni Albers Eclat

The ruleset of the main procedure draws white triangles on a black background, randomly assigning rotation values (in multiples of 90 degrees) as it lays them out. The piece is generative and is never exactly the same each time it is executed. The pink rectangles on the right are not generative and will always be the same.

Agnes Martin – After a conversation about procedural art and my generative coding experiments with my course instructor (Hi Erin!), she mentioned Martin’s work. It’s new to me and I’m really excited about it! She was an abstract painter with a keen knack for grids and procedural, repetitious forms that I think would be perfect to explore in my own visual programing experiments.

The bulk of my time in studio this week was devoted to experimenting with generative art in Processing. Coding pieces that conform to the WOVNS platform constraints of resolution and color. This single piece I’m sharing below is one execution of a script that randomly assigns colored squares and prescribes exact bottom and right border patterns. I’m inspired to research more geometric artists and weaving patterns.

I have decided to pursue a project exploring the intersection of pixels as threads, or screen resolutions “re-represented” with threads-per-inch. I will use Processing code as art material to create generative art pieces conforming to some specifications of the WOVNS platform. This way my selected generative art works can be fabricated as textile and fabric art.

My research and explorations need to go in two directions. One one hand, I must learn the technical specifications of the WOVNS platform, and on the other, I want to explore art and artists that will inspire me.

Technical Explorations

My technical research consists of exploring a set of generative art examples on from WOVNS. They have a number of tutorials available for users to choose from, and the Processing section describes a free set of Processing scripts that one can tinker with to see how it all works.

Next I watched a Video Tutorial for Processing and WOVNS computational textiles platform with artist and professor David Mellis. It was a nice beginner tutorial demonstrating how to make your own generative art code under the constraints of WOVNS particular pixel resolution and color palettes.


Since I am interested in making generative and procedural art for textile production I have been digging into the work of some exciting artists that intersect these themes in their own work.

Sol LeWitt: The American conceptual artist was unknown to me until this Summer, but that only proves my naive art background. I’ve since become very excited about discovering his work, especially his wall drawings, patterns, and rule-based art works. I would love to read more of his instructions for drawings and about the specific nature of his procedural art and it’s potential intersection with code as art material.

datamoshing: In an effort to explore how fabrics could mimic screens, I’m reading about an art trend of a few years ago called datamoshing. This technique blends compressed digital videos or photos together, removing keyframes from a file so the pixels smear and digital artifacts are enhanced. Another form of glitch art. I found interesting article about Russian photographer Polina Eframova, who recently shared a similar set of datamoshed photos, captured manually, rather than executably with code, by running digital video through an older PC that was not fully compatible with her camera software.

Phillip David Stearns: The artist behind Glitch Textiles and a throw blanket I found for sale on Adafruit’s website, Dark Code Throw. His goal seems to be fabricating woven-looking patterns that are produced in his artwork into physical, tangible weaves. This seems similar to what I might pursue for a final project – code generated fabric arts.

A&HA 5128: Research, Explorations, Materials, Tools

Currently my project areas of interest center around the transformation of pixels into physical matter. I’m kicking around the term “re-representation” of pixels, since pixels are often a digital representation of natural matter, they might then be considered as reconstituted or “re-represented” if we made a pixel form again out of natural matter. It all sounds strange, but I’m feeling engaged all the same.

What are some areas that I can research related to my project ideas?

I’m currently scouring the Web for 3D build projects that are communicative as one way to explore this idea of physical pixels. So far I am really enjoying Chris Fenton’s “Pixel Weaver” which is an “entirely mechanical, punch-card driven, bit-mapped display”.

There are two main components to the machine – 1) a 32-hook Jacquard-style punch card reader (suitable for mounting over a small loom or any other device in need of mechanical control), and a 6×5 pixel, black and white display.

In his documentation, Chris cites inspirations from a LEGO builder using the handle Ancient James who has also built a flip dot display with a LEGO “punch card” reader for input. The build is pretty excellent and was featured on Hackaday.

All those punch card references got me thinking about jacquard looms. I wondered what it would take to build my own mechanical loom. Some searching led me to an interesting artist named Pamela Liou, who is a Project Resident at Eyebeam and is currently researching the design of a DIY jacquard loom. She calls the project Doti, and it is still in development, but I am eagerly awaiting project updates.

What are some concrete things that I can explore during work time in our next class?

I think that I will likely attempt a rebuild of the single pixel mechanism from Ancient James’ LEGO flip dot display. I would be fun to reverse engineer the mechanism.

I will also explore the WOVNS computational textiles platform. They offer short-run access to jaquard looms under specific resolution and color constraints. Thinking about looms, textiles and fabric arts makes me want to explore the tool, which I came across this Summer when delving into resources shared by the Processing Foundation. It could be interesting to explore their tutorials for using Processing to generate textile patterns, which they could fabricate for a fee.

What materials do I need now?

At this stage I feel that my potential materials are pretty straightforward: LEGO technic parts if I choose to explore a display, and/or Processing code if I plan to explore patternmaking on the WOVNS platform.

What tools do I need now?

My tools are one in the same as my materials at this stage: LEGOs and/or the Processing code editor.
