Uploaded as a request. Looking for parametric curve definition to produce this kind of imagery, as it is now an approximation. The idea is the following: in technical drawings for example, giving an object a particular tone is achieved by hatching. Hatching may consist of parallel lines, drawn with the same line weights. But how could someone make an angled hatch in a polar way -meaning anything but concentric circles-? Still keeping a consistent tone at the end. Any ideas?Archimedean spirals are a close match if the width of the stroke is 0, but not this case.

Let's see if we can pop in the game factor, starting a new series. The challenge: there is a simple shape in the given clipart; draw your part to it so it represents anything that come to your mind. Looks like a bird? Draw a beak, a nest, some eggs perhaps. Reminds of a futuristic vehicle? Go for it! There is no limit, except the shape you see needs to take some part. Good luck!
