Last night I came across the famous Vertigo poster by Saul Bass, which I really like. And it got into my head to figure out how the spiral was done. A couple of hours later I had something that wasn’t too far from it:
If you’re just curious about how the spiral is drawn, it’s simply an ellipse that is rotated and shrunk at each step. The rotation and shrinking steps decrease asymptotically towards the central ellipse. I’d be quite interested to know how Bass did it.
