    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.

Golfed-ish... Maybe learn some new techniques fromit IDEK, https://www.dwitter.net/d/7041
u/BirdsTweetCodersDweet

See the link in the comments of that one as well. Shortened it some more.
u/triclops200

The first one had golf that kept the output the same, but the second has output changes (the /3.6, for example, was there to approximate center of screen y), otherwise, good golf

Note that "540" is shorter than "w/3.6" ;)

If someone can shave 2 characters off, we can invert the colors! Like in d/7011

u/akm

here, I shaved off 10 chars: with(x)for(fillStyle="#FFF",i=0;i++<44;lineWidth=44)beginPath(arc(960+S(a=t*i/11)*(d=i*t*S(t)),540+C(a)*d,i*3,0,7),fill(stroke()))

Does anybody know how to make this actually bounce off the sides in 140 characters?
u/BirdsTweetCodersDweet

Better resolution if you want : for(c.width|=i=999;i--;x.fillRect(M.min(1870,M.max(0,960+400*S(a=t+i/4)+800*S(t))),M.min(1030,M.max(0,540+400*C(a)+400*C(t/3))),9,9))M=Math

Great!
u/davidsharp

@Xen, you should totally fork it, that looks great
u/New_Core

on Xen's version can remove t+i to i ... no need to spin it if it looks like a line.
