> Quote - The formula for a squircle has an exponent in it. When this value is 0 you get a square. When it is 1, a circle. In between 0 and 1, you get the squircle shapes I've been showing. > > But what if you go past 1? Fascinating. At 2 you get a diamond. (Which is still a square, but rotated 45 degrees.) > > And at 3, a new shape which is called an astroid. It is a diamond with circles cut out of its sides. Of course you can dial in any in-between values you want. > > Past 3 it just becomes a narrower astroid - a diamond with squircles cut out of it. > > Left to right, squircle + circle, astroid + circle, astroid + astroid.

The example on the right looks like a quilting pattern called Cathedral Windows..
