    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.

i actually posted this on accident looking for a cheaper way to get randomish looking numberss than Math.random()
u/iverjo

Good quest
u/iverjo

In some cases T(veryLargeConstant*x) or S(veryLargeConstant*x) can look random enough

Golfed it a bit: c.width|=0;for(i=300;i--;x.fillRect(960+(C(m)+S(a=i%40))*200,540+(S(m)+C(a))*200,20,20))m=t+(0|i/20)/7*Math.PI

WAIT shaved off two more characters: for(c.width|=i=300;i--;x.fillRect(960+(C(m)+S(a=i%40))*200,540+(S(m)+C(a))*200,20,20))m=t+(0|i/20)/7*Math.PI
