    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.

I see that the q variable can be edited away to shrink it a little

Golfed and slightly cleaned at https://www.dwitter.net/d/5543. Have fun with the extra characters!
u/Bugsy

(cleaned is referring to some slight blockiness on the right side of the animation, not the code. My code is much uglier :P)

Neat! TIL Javascript accepts python notation for exponents.

u/alien

wait what is going on here D: , could explain this x[i=frame] and T=x[i] plz
u/alien

How can you add T a numer, isn't T a defined function?
u/iverjo

frame is a number that starts at 0 and increases by 1 for each frame (this is actually a somewhat "hidden" feature in dwitter, and can be used as an alternative to t). T is initially a defined function (by dwitter), but the code in this dweet sets T to something else before a number is added to it. x[i=frame]=300 has the same result as i=frame,x[i]=300 because i=frame returns the new value of i

golf'd slightly harder on general principles: i=frame;for(j=1080;j--;x.fillRect(i,j,1,S(k/9),x.fillStyle=R(k,j,i)))for(a=b=0,k=35;k--&&a*a+b*b<4;a=c)c=a*a-b*b+i/540-2,b=2*a*b+j/540-1

This is freaking amazing. Even if it would have taken you 1000 characters

Thanks bakkot! I golfed your version even further down to 134 characters: for(j=1080;j--;x.fillRect(i=frame,j,1,S(k/9),x.fillStyle=R(k,j,i)))for(a=b=0,k=35;k--&&a*a+b*b<4;a=c)c=a*a-b*b+i/540-2,b=2*a*b+j/540-1

Feel free to play with the colors! There's room for improvement

I must commend you! Did my research and got a working mandelbrot, but to golf it to 140 and get the speed is very very difficult! Wow. I will study your dweet now :)
