    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.

this tunnel looks so clean!
u/iverjo

Thanks :) My aim was to create a vertical camera tilt effect. I ended up just moving everything up and down. Kinda resembles tilt ^^

Color version, a minified version of myJS's suggestion

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
u/iverjo

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
u/hamptonio

That's a work of art man
u/SpecialAgent

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 :)
