    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.

You're more than welcome to mess around with this code. What exactly do you want help with?

a bit golfed version.. p=3.14;j=(t*1920)/p;z=Math.random;r=z();m=z();x.fillStyle=R(T(t)*192,96/m,96/r,.9);x.fillRect(-j%1920+1680,j%1080-8,250,64)

Thanks! I was meaning to check how to declare functions in javascript... Although I find that at least 3.146 is needed to closely replicate pi, so ill usually take the 3 extra chars

ok nice dweet though

appreciate it

I wonder is there's a tag for fps graph glitch-outs.
