    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.

E.g. for D=[7,2,5] and L=5 it produced 5/i^7

😂 the code is a mess but its useful. The ascii vomit encodes the valid next char to speed things up.

I think this might have been drawn on Dwitter before, but I can't find that dweet right now. I love the simple design!

Me too! It's minimalistic.
