    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.

Thumbs up for using the error output instead of the canvas. :)

golfed down by 2 characters t||(p=0,n=1);for(i=1e5;i--;)p+=(n%2?4:-4)/(n++*2-1);throw p
u/BuRRak

nvm, 4 characters, dwitter should have edit comment feature t||(p=n=0);for(i=1e5;i--;)p+=(n++%2?4:-4)/(n*2-1);throw p
u/BuRRak

Oh no, just noticed it throws negative pi, just swap 4 with -4

Color Preview - use R, G, B to increase the RGB values and shift + R,G,B to decrease them

golfed it down to 99 chars: with(c){onkeydown=u=>[e=u.code[3]]=e+u.shiftKey?-1:1,style.background=R(r,g,b);throw r+';'+g+';'+b}

Or. with akm's modifications: with(c){onkeydown=u=>[e=u.code[3]]=e+u.shiftKey?-1:1,style.background=R(a=r%255,d=g%255,e=b%255);throw a+';'+d+';'+e}

The most awesome thing about Dwitter is how the quality of the dweets is constantly increasing. Everybody is learning new tricks and techniques from one another and doing more and more awesome stuff. :)
