Why spirals? Because I can vary the density of my lines in any area without cross-hatching and without lifting the pen. This lends itself to the kind of repeating procedures (program) I’ve been thinking about for quite some time. But curving spirals (where the radius of the circle being drawn continuously expands from or contracts toward the center) don’t fit nicely no matter how cleverly you arrange them – they always either overlap or leave empty spots. So I coded rectangular spirals where the line started at the center of the “tile-space” and the line continued to turn and lengthen until the segment hit the perimeter of the tile:
Here’s an image of my screen input as of January, 2019:
I could communicate an image by controlling my input parameters so the image was drawn in a single layer of spiral tiles, and/or I could overlap the tiles horizontally and/or vertically, and/or I could draw multiple layers of tiles in colors and I could overlay tiles of different diameters. I experimented and produced a number of interesting-to-me drawings using ink and paint and woodcut. Here are some of the drawings I made between July and October.
