@bit101 a version I made for the bbc micro a few years back. I do like that coding up optical illusions like this means you know for certain it's not what it appears to be... but you can't unsee it https://mastodon.me.uk/@bbcmicrobot/109763774911592856

@bbcmicrobot An idea I had out on a run. It's way too slow to fit in 30s, but if you run it with the rocket it doesn't draw the lugs. The picture is just circle to test it out.
The lug logic turns out to be simplified by taking X/Y mod the grid size, and swapping them if X

@bbcmicrobot Hilbert curve on -1,1]x[-1,1] mapped to a circle using a mapping from [https://arxiv.org/abs/1509.06344
Analytical Methods for Squaring the Disc
We present and discuss several old and new methods for mapping a circular disc to a square. In particular, we present analytical expressions for mapping each point (u,v) inside the circular disc to a point (x,y) inside a square region. Ideally, we want the mapping to be smooth and invertible. In addition, we put emphasis on mappings with desirable properties. These include conformal, equiareal, and radially-constrained mappings. Finally, we present applications to logo design, panoramic photography, and hyperbolic art.
