    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

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

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…
