    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.

If you declare your vars you can't get this to run reasonably well t||x.fillRect(0,0,w=2e3,w);let j=1,m=x.getImageData(0,0,w,w),g=m.data;for(;j<8e6;j+=48+g[j])g[j]=255-g[j];x.putImageData(m,0,0)

you can** get this to run

Sweet, thanks

Your code doesn't grab the data every frame, it didn't even cross my mind to only do it once.

Or just run it in Firefox ;-)

Saved another 7 chars (I think) from the uncompressor!

u/tomxor

Oh neat, 8 i think, I thought of moving _ directly into it's reference, but combining it with the condition is way better.
u/tomxor

This has also past the threshold at which d/9207 stops reducing (even when moving _ back into a reference.)
u/KilledByAPixel

I think it might be possible if the data was packed tighter, maybe we can do better then 7 bits per char
u/tomxor

yeah i've been secretly thinking this but haven't come up with anything particularly amazing yet... you only actually need 6.75 bits if you ommit the lower 32 control chars including space and tab, but it's too messy to mix in the combinations from other chars, probably need to lose some useful chars too.
u/tomxor

I meant tab and newline not space, both of which are pretty useless for dweets.
