    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.

Very cool idea by TGY, playing around with the concept

u/Agnes

You can even optimise this by adding a=a.filter(e=>e>0) if X*Y is replaced by (e.x-960)*(e.y-540), which I guess doesn't matter at all but feels better somehow if someone were to sit around clicking on this millions of times

FYI: This dweet looks different to me, depending on whether I'm viewing it on iOS/Safari or on Chromebook/Chrome. On iOS, there's more detail even in the dark areas. I'm guessing it reflects a difference in how the 'hue' is implemented, but I dunno.
u/sigveseb

Awesome! Love dweets that expose browser implementation differences like this. Looks cool too :)
