    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.

u/BirdsTweetCodersDweet

why do you assign your variables like this ?
u/BirdsTweetCodersDweet

a = 9 ; b = 7;
u/BirdsTweetCodersDweet

It's unnecessary, and makes your code so much longer, which matters if you try doing more complex stuff/dweets
u/BirdsTweetCodersDweet

Look - you can even add a fillStyle in there now: for(i=3;i--;)x.fillStyle=hsl(${S(t)*99} 90%50%),x.fillRect(500+i*400+S((t*5)*i)*100,600+C(t*5)*100,10,10)
