Requesting cool fractals or optical illusions
Something about a sharp blue and red contrast.
My grandma had this blue-painted wooden sign for her kitchen. It had a red hard with a black drop shadow. The heart would always move a little independently with the background. Blew my fucking mind when I was little. I don't even think the illusion was intentional.
Here's the golden dragon curve, with different constants derived from the golden ratio. Probably my favourite fractal generated without complex numbers.
...And zoomed in quite a lot. One of the interesting things about the dragon curve is that none of the lines overlap.
I didn't name it, I just wrote a script to draw it. I don't understand the obsession with dragons in the naming of fractals in this category. Here, have a levy dragon.
