    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.

Inspired by u/anotherkitten u/21medals This is more likely to draw something by focusing on the [x,y] = f(t) solution space and further reducing that to interesting ones by manipulating allowed input tokens.
u/tomxor

Familiar yet different every time :)
u/tomxor

Trust me, it will draw :P every time the comments bounce it's found a solution and assigned it, but not all combinations draw anything visible.

Trying to eval a random string, pauses when its compilable

u/21medals

Most of them are just one big comment or one long string though
u/katkip

nice!
u/21medals

99% copied from tomxor's dweet though!
u/tomxor

eWuW='.,gttb/PIdd ]I]8fte6?Abnu80<~pI~u' It's still quite impressive that it can find any... I guess reducing the length to 40 substantially increased the probability. The next logical progression would seem to be to let it accumulate shorter evaluable strings and compose a larger one from them.
u/tomxor

If you can also fit in the requirement to reduce entropy then you have the seeds of life inside a dweet :D
u/katkip

yeah
u/katkip

it can be faster with another for
u/tomxor

I tried that but couldn't fit it, so I did the opposite - reduce the search space - I made one that constructs expressions for f(t) and does the canvas bit for it so it actually draws: d/12492

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)

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

Trinitron #crt #scanline #fractal

u/tomxor

Finally resorted to UTF8. This is a reasonably accurate slow motion aperture grille scanline animation... Although if run very slow you will see it's not simulating 3 electron beams. t=fps (scanline) w=width (subpixels) the later must be a multiple of 3 and 5. Use X, Y and floored F to plugin your own fractal!
