    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.

To save one character (avoid the exclamation mark), you can do t?0:X=[]; or X=t?X:[];

Basic Christmas tree! :)

u/Atti

A more elaborate version, that's currently too long: for(i=1085;i--;){x.beginPath();x.fillStyle=i<5?i%2?"red":"white":"green";d=i/3+80*T(i%300/260);i>5?x.rect(950-d,i,2*d,1):x.arc(900+i*S(i)*100,400+i*200,50,0,6);x.fill()}
