function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

    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.

function u(t) {

t?(A=X+C(R=Math.random()*99)*10)*A+(B=Y+S(R)*10)*B<9e4&&(X=A,Y=B):X=Y=0
x.fillStyle=`hsl(${t*6},50%,50%)`
x.fillRect(X+960,Y+540,10,10)
