    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.

Which browser and OS do you use? I tried Chrome and Firefox on Linux and Mac but unfortunately they don't appear.
u/yokljo

Interesting, I'm using Chrome on Linux. Maybe I have the right font installed...

Thought it could do with some golfing

u/Xen

can lose the ; by putting fillRect outside the brackets.

I really liked the idea of shading the flag, but my remix didn't fit on dwitter: https://codegolf.tk/a/168

This was only running at 20 fps on my phone when I wrote it so results may vary

u/Galaxtone

.... Maybe add t/=3
u/Galaxtone

Looks much better with that

This does some whack stuff on my desktop Chrome, which you may see if you attempt to edit the code (put a space at the end or something)

u/yokljo

Here is the minimum requirements for the weird Chrome bug to occur: t<.1?w=c.width=100:d=x.getImageData(0,0,w,w);x.putImageData(d,0,0)
