Show HN: De Jong Attractors

Yesterday's post [1] about the "Kaos" screensaver led me down a rabbit hole and I ended up implementing this demo of Peter de Jong's attractors:

    x' = sin(a * y) - cos(b * x)
    y' = sin(c * x) - cos(d * y)

I added a little flair by blurring the point based on its distance from the previous point (how "fast" the attractor is moving).

I added a bunch of controls with a lilgui control panel. Try it out! Works fine on mobile but easiest to play with the controls on desktop.
