Variations on Knuth’s Twindragon

A couple days ago I wrote about Donald Knuth's expression for the twindragon fractal as a sum of powers ofb = 1 -i.

Simone Conradi made a nice animation replacing (1 -i) with exp(2it) (1 - i). The animation loops over values oft.

Here's what you get whent = 0.3.

And here's what you get whent = 0.4.
