Here is Irradial done on a black tile, with a bit of fractalization. Again, I wanted to keep the string simple so that I could just enjoy drawing the tangle. I also wanted to experiment with using Copic markers to shade around each section. It didn’t quite get as dark as I wanted, so then I added black charcoal pencil around the borders and at the center line for each section.
I combined several different techniques on this tile. I didn’t start out to make a Monotangle. Originally I was going to put a bunch of different tangles in the spaces between the largest Ruutz. But I just got into the zen of it and fractalized Ruutz down three iterations. Then I decided to color the various levels. The top level I colored pink, the second was a lime green, and the smallest was a light blue-violet.
