    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

Is everyone percieving the same thing? it's both abstract and specific for me.
u/taupelink

for what it's worth, i was going for "reeds at the water's edge." not when i began, mind you...just at some point while i was experimenting, it started looking a little like that, and i coaxed it further in that direction :)
u/taupelink

(not perfect, obvs...the water is kinda churning at its edge, and the green isn't especially natural-looking. ¯\_(ツ)_/¯ )
u/C010011012

so good
u/tomxor

Yup, "reeds at the water's edge." is what I see too, I like how it seems to remain very abstract at the same time as being detailed and specific.
u/tomxor

I suspect #abstract-impressionism might be the correct definition? I'm insufficiently educated in art to be sure.
