    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.

Second attempt at an old school tunnel effect

u/danny@hille.dk

Uncompressed code: t||(I=new ImageData(c.width=w=255,h=160));for(i=w*h;i--;I.data.set([,,(p+t*w&w^w*a*1.6+w-t*w&w)-p/9,w],i*4))a=Math.atan2(X=-.5+1*(i%w)/w,Y=-.4+2*i/1e5),p=w/(Y*Y+X*X)**.5*.5;x.putImageData(I,0,0)
u/danny@hille.dk

#tunnel
u/danny@hille.dk

first attempt: d/23462
u/danny@hille.dk

Javascript garbage collector is struggling, when you create a new ImageData at each run, which results in some nasty stuttering. t||(I=new ImageData... fixes this issue
u/magna

This worked for me: I=x.getImageData(0,0,c.width=w=255,h=160) (no need for t|| check)
u/danny@hille.dk

u/magna while getImageData does not hit the garbage collector quite as hard, it takes about 1.3 times longer to execute, wich amounts to 53 fps, while t||(I=new ImageData... runs at a constant 60 fps (on my old 2014 macbook pro :-))
