Super-trippy interactive visualizer feels like getting high for free

If you don't live in a state that allows recreational marijuana yet, perhaps this fabulous Hopalong Orbits Visualizer by Iacopo Sassarini will tide you over till then.

Sez Iacopo:

These orbits are generated iterating this simple algorithm:
(x, y) -> (y – sign(x)*sqrt(abs(b*x – c)), a -x )
where a, b, c are random parameters. This is known as the 'Hopalong Attractor'.

Note: you might get a touch of vertigo on a fullscreen while moving your mouse around.

FYI, it might amp up your HPPD, too!

If that was fun for you, this Android live wallpaper might also be to your liking.
