This was one of my entries into a contest to produce “creative and meaningful artworks of the Arabic numerals (from 0 to 9)”.  I started doodling these designs with just a black biro, on A6 sheets of paper. They were completely unplanned and evolved organically, taking about a day to complete (although not done all in on go but in sporadic bursts). I think they were an outlet for my latent creativity during a period where my job offered little such stimulation.
