    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.

Longer, but better (153): for(i=2;i--;)x.beginPath(x.fillStyle=R(i?w=255-(s=C(t*2)*127+128):s,0,i?s:w))|x.arc(960+80*S(i?π=t*5:n),540+80*C(i?n=π+3.14:π),80-30*S(t*8),0,7)|x.fill()

Inspired by the "second phase" in http://slicker.me/javascript/yinyang.htm. Thank you to Joey, Veubeke, and Athos from Discord for the last ~100 chars golf (I still golfed it from 480 chars to 240 though :P)
u/BirdsTweetCodersDweet

Putting a=S(t*2) also makes the color transition better, but that would be 142 chars
u/pythech

just golfed the a=S(t*2) version
u/pythech

golfed the 153 chars version too
u/pythech

I don't feel comfortable owning your work just because I could golf it though. I just put them as remixes but I can delete them if you want and you can repost it I guess (I don't use discord, bummer, maybe I should?).
u/joeytwiddle

I also feel uncomfortable owning your Debian logo. But that's how things go on Dwitter these days! u/lionleaf was talking about a remix-in-comments feature. Perhaps this is part of the motivation.
u/pythech

Cool idea! Yours was a proper remix though IMO, which involved changing the code and so on. Also great job on that btw :D
u/BirdsTweetCodersDweet

No problem pythech, just post the links here, and give credit :P
u/BirdsTweetCodersDweet

And yeah, join discord

Anyone wanna have a go at trying to make this rotate, to give it a kinda trippy effect?

u/joeytwiddle

I thought this might turn into the Debian logo!

It did! <3

3D 8-loop... But which way is it going?

u/BirdsTweetCodersDweet

Kinda reminds me of the Visual Studio icon tbh :D
u/Tourghool

Judging by the code, bigger side is closer ;)
