    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.

Turning Rössler Strange Attractor, a system of three non-linear ordinary differential equations with chaotic dynamics and fractal properties. Some people see this turning clockwise, some see counterclockwise due to the bistable optical illusion (search "Spinning Dancer" for explanation). #attractor #illusion

u/rodrigo.siqueira

The rotation effect trick X*C(t)-Y*S(t) was "borrowed" by Frank Force KilledByAPixel's #Lorenz Attractor: from https://www.dwitter.net/d/14752
