I was just doodling with some shapes to try out the improved 'expand stroke', and this is what emerged. It started out as a coupe of cogs and an ellipse and a few Boolean operations, followed by a bit of inspiration and tweaking of nodes.
When I was knee-high to a sketch pad, my grandfather -- a talented draughtsman -- told me to invoke inspiration by making a random scribble and seeing what it suggested. Good to see the technique still works in the digital age!
