    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.

Very clever to use transform here! Thanks for improving this.
u/tomxor

Thanks for starting the idea, was really fun making this one.

can in theory generate almost any dweet, but will practically never draw a single pixel

if this does actually manage to draw anything for someone (or at least not throw an error), please let me know

There are 128**140 == 1.0218702384817765e+295 possible Dweets :) If one dweet eval takes 1ns (being very kind) that will take 128**140 / 3.154e+16 == 3.24e+278 years to permute (that's thirty-two duononagintillion four hundred unnonagintillion)
u/tomxor

I suppose I more useful estimate would be the probability of an evaluateable string string... No idea how though.
