    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.

nice!
u/DirtyDan

Don't know what I was thinking having "+960+C(t)*i" in the first arc parameter -_- ... 11 extra characters!
u/DirtyDan

nvm, the +960 was necessary, not the "+C(t)*i"... 7 extra characters.
u/Purpzie

This is so beautiful.

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}

Mostly an accident, but it looks cool anyway

u/DirtyDan

Pretty sure most dweets are, lol
u/artfarnaa

Every artist from every domain says same thing. Nothing great emerges without the author saying it was just an accident.

Not always true in creative coding/demoscene tbh
