How do you even spin along a spiral? A spin that loops on forms a circle tracking the same point. The only thing you can do with a spiral is to follow its path.
Spirals are infinite. They go along a path that virtually never ends. The path, visually, is continuously shrinking into a potential point and its one of the easiest ways to visualize infinite, like fractals.
Whenever I read or see stuff about the Golden Rectangle and the spiral thing, I always feel like i'm tripping balls because that shit makes me feel existential as fuck
