    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.

99% copied from tomxor's dweet though!

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

You can save 16 chars from the original just by assigning constants you use a lot to variables:f=500;y=255;M=Math.random;x.fillStyle=R(M()*y,M()*y,M()*y);x.fillRect(S(t)*f,C(t)*f+f,5000,50)

I'm not sure how this is supposed to work... See for example d/9677 -- your tool gives "eval(unescape(escape𒡦𫱲𚁩👣𛡷𪑤𭁨𧠽𜀻𪐭𛐻𮀮𨡥𩱩𫡐𨑴𪀨𮀮𩡩𫁬𚀩𚐩𠰨𨐽𭀭𪐩🠰𙠦𮀮𩑬𫁩𬁳𩐨𞐶𜀫𚁘🐨𪐪𞐶𜀭𪐪𪐩𚠪𛠵𚡓𚁡𚐩𛀶𜀫𪐬𚁳🐲𝐭𚁓𚁡𛐱𚐪𚁢🐨𜐭𚀨𦐽𪐭𝀸𜀩𛰴𞀰𚐪𚠲𚐪𚠮𝐩𚐪𚠴𚠲𝀩𚡃𚁡𚐪𨠬𬰬𣑡𭁨𛡡𭁡𫠨𦐯𦀩𛀰𛀷𚐻.replace(/u../g,'')))" which is 225B
u/f8f82804

This is on Firefox 64.0, 64-bit, on Ubuntu. This may require a browser that counts characters differently?
u/metamero

just paste the compressed code on new dweet, it works. to remix you have to delete disabled atribute of post button on inspector. this is a #bug on dwitter page's char counting, but server counts right (number of unicode glyphs <= 140) so posting astral unicode chars works fine. there is this discussion on github... but the status now is at least inconsistent.
u/f8f82804

could you point me to that github discussion?
u/f8f82804

ahhhh yeah i see what you mean about inconsistent -- the new dweet shows 225/140 but still allows it to be posted, while the remix button is disabled with the same code
u/f8f82804

personally, I thought that this was intentional, and that the char counting was counting 16-bit char codes, not unicode code points (e.g. the difference between charCodeAt and codePointAt)

this doesnt like code like thsi: x.fillText('⬛⬜' ( I get a short output with an unterminated string constant errro on the dweet, but it finishes comprssing with code like this x.fillText(['⬛','⬜'] Which takes me up to a 140B output, yet doesnt run, Aggh, Im so close...

Fantastic job! Love the use of the cos(t-i) aka backface culling as alpha value of the fillStyle to sort the splats and skip clearing the whole canvas. That was THE killer optimization to fit in 140 chars.

oldspork These symbols are just what unicode decides his binary data can best be represented as in text. The real magic is the charCodeAt part of their code.
