    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.

Modify 20 in 20+t/7 to start at higher or lower complexity

u/DataMeta

Different start points change the order in which "pixel" sizes stack resulting in different sequences

wow this is weird - on amoled n-43 makes orange sand and n-42 yellow

more dynamic wavebreak that aligns with perspective: for(j=20,h=96;h--;)for(v=54;v--;x.fillRect(h*j,v*j,j,j))z=S(t&h/(v*2))*255,x.fillStyle=R(n=v*4<=h-t*9%(v+1)?0:255-z,n-64,v*3>h?64:255-z,.01)

I like the feel you created here. Almost like a city pop album cover, but it moves!
