    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.

Superb! Golf the end with i*(t%2>1) or i*!(t&1)
u/rodrigo.siqueira

Thanks @joeytwiddle for the golf trick. i*(t&1) also works and it's even shorter. And I found that t%4>2?... can be converted to t&2?... It works as a counter to change the function each 2 seconds.
u/yonatan

Also, since T and S take the same arguments (t%4>2?T(b+t):S(b+t)) can be (t&2?T:S)(b+t)

cool! also cool it's #compressed using the UTF-16 surrogate pairs method =]
u/joeytwiddle

It sure is! I gave your compressor a try.
u/joeytwiddle

This dweet was first attempted by BirdsDweet and myself in February 2018.
u/joeytwiddle

We never really finished it, so this is as far as it got. I publish it now, because Slack has now changed their spinner!

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...
