Processing patterns - 02.12.2020

   processing

I first got a computer back in the early 1980s - a Sinclair Spectrum. You either copied programs from magazines by typing them in on the little rubber keyboard, or loaded saved programs from a cassette tape. After doing both of these for a few weeks, I started to read the manual and slowly learned a little programming in Sinclair Basic.

This was the first thing I made which ran successfully. Just drawing a line which followed a sort of square spiral and relying on a drawing function which only turns on a pixel if the original pixel is blank. It's fascinating watching simple rules produce complex outcomes. It was one of the first things I tried to reproduce when I discovered the processing language.

sample1 Hitomezashi stitching - wow! It's a variant of the Japenese sashiko embroidery technique which produces inticate patterns. According to Wikipedia: "Coming into existence in the Edo period (1615-1868), sashiko embroidery was first applied to clothing out of a practical need, and would have been used to strengthen the homespun clothes of olden times."

Annie Perkin's (@anniek_p) twitter posts explain that the stitches can be decided in many ways: at random, using your favourite numbers in binary, whatever you please. They can be symmetric or not. Whichever you prefer. Colouring in the areas between the stitches makes for interesting patterns. Have a go yourself with my app what I made (not so good for mobile use):
