    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.

Btw - you can change font to '14em a' or similar to save some bytes
u/hypothete

thx sfz!
u/stiaje

If you don't need a very exact pi you can also shave some bytes off.

Hello guys. I need ideas on how can i optimize this thingie :)

u/lowpoly

and yea, the k*=(i<=0||i>=w)?-1:1; l*=(j<=0||j>=h)?-1:1; part concerns me most
u/joeytwiddle

Well this is 2 chars shorter: if(j<=0||j>=h)l=-l; // and this is the same: (j<0||j>h)&&(l=-l); // You could also drop the four =s for a small loss in quality.
u/sigveseb

Looks nice!
