Nuther twist on the idea of novel means of depicting an image using lines (click on the pic for a larger version). The lines in this image actually form a tree. It looks to my eye like cracks in a surface, and if I had time, I'd work up a rendering which brought that out.
This is actually a portrait of Katherine Mansfield. I had a small literary crush on her in my bookish youth. It was faintly odd to discover upon moving to New Zealand that I was actually living in her home town.
