Ah, these are creatures of themselves, the offspring of lines. They are explorations of pattern  mixed with a cartoon mentality, in service of ambiguity and absurdity. I've been playing with these forms for years, beginning in the early 70's. Armed with a Rapidograph technical pen, I filled a few spiral notebooks with endless variations. I put them aside for 10 years and then I began new volumes of Doodle Books. Those books contained a mix of styles and content. The idea was not to prejudge its intent or content. One subset of the content was this style of drawings, based on the abstract interaction of lines and the images they merge into.
