I love how when doodling, your conscious brain is turned off and you can be surprised by what you come up with. During a boring unrelated meeting I sketched a bunch of little things that looked like they came from one of my college invertebrate zoology texts. Those sketches were at the back of my mind when I started this giant coil form. I love the way it came out. It is half sea creature, half underwater mine or some other man-made thing.
