Twin Dragon Fractal and the twin version of Peano-Gosper Curve. #fractal #dragoncurve

u/rodrigo.siqueira

I found that this seems to be similar to the matrix described here: https://www.youtube.com/watch?v=fFIyqMiycs4 (Twin Dragon Fractal - Order from Chaos - visual construction)

I also found a geometric iterated construction of the Twin Dragon Fractal here: https://onlinefractaltools.com/draw-twin-hei…

<code>for(y=i=5e5;i--;)x.fillText(0,y=y-t>>1,t-=1630*(t&1)-y)</code> to get an image fast, but then it's not very responsive.
