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.
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'.

FYI, it might amp up your HPPD, too!
If that was fun for you, this Android live wallpaper might also be to your liking.
