And squares whose sides decrease by the plastic ratio (about 1.324). At one moment the spiral of five squares make one full turn.

Now for equilateral triangles whose sides decrease by the plastic ratio (about 1.324). A slow version so that the plastic pentagon is clearer https://en.wikipedia.org/wiki/Plastic_ratio#Plastic_pentagon

The plastic ratio is probably not as well-known as the golden and silver (√2) ratios?

Now squares increasing by the golden ratio

Looping animation of silver rectangles with sides decreasing by 1/√2.

I did the animation with Toon Boom Harmony and then did all the digital "ink and point" with the Pixquare app, which is really great!

@MashedMen Thanks, I was going to do more but the existing construction does not generalise well. Here are the key shapes for twelve-pointed stars.

This one has regular octagons and rhombuses.

This animation has two different kinds of white shape. Curiously, I made this before the ones with only one kind of white shape. This one has two sizes of squares.

Eight- and four-pointed stars using different angles.

No scrolling needed for eight- and four-pointed stars like this classic stars and crosses pattern.
