So, a friend recently completed her PhD with a dissertation relating to cyber security, and I was commissioned to produce a piece of art for her as a gift.
She'd seen me doodling in many meetings, so an ink drawing involving a rat seemed most appropriate.
The finished piece is an ink wash drawing on watercolour paper.
I used some elements from an earlier painting, because I really like the pose of that rat and because the base 12 abacus seemed appropriate for the recipient. She also appreciated the very old-school paper punch tape.
There were moments of deep frustration while drawing this, when the paper was absorbing the ink washes in unexpected ways. I nearly threw it into the recycling more than once! Happily it did finally work out in time after multiple layers of washes and hatching.
