Just enjoy the peaceful bliss of neon rain as it pours down.
Description from store
Not only does this extension give you a beautifully calming view of rainbow droplets in its contrasted abyss, it's programmed to be as naturally unpredictable as real weather.
There's no telling what weather will do, hence the butterfly effect. So each drop of neon rain has a 50/50 chance of duplicating or disappearing.
On top of that, the color of each droplet changes and varies depending on many factors. This allows you to have the most interesting experience possible while gazing into the gentle atmosphere created not by me, but by pure luck.
If you want a calm break for your personalized environment, tailored by randomness itself then this extension is exactly what you're looking for.
