    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.

The Rössler Attractor (printed version). Here is a plot print of this image: https://www.instagram.com/p/CHJQov_Fly_/ The vectorial svg file to print was generated using Turtletoy here: https://turtletoy.net/turtle/c82f5e2af3 #plotter

Comment by "themarinus" (he printed the image using a pen plotter): "The Rössler Attractor. This beautiful design is made by Rodrigo Siquera over at turtletoy. Loved it so much that I turned his line art into a plot! 160 grams A4 black cardstock White acrylic ink, with a 0.5mm line width."
