OK.It's.Raining.Men are not what you think it is - no men involved. Hallelujah! It is just a neat configurable rain effect for your desktop.
The raindrops can be individually customized and set to display very gentle rain to very spectacular rainfall; it all depends on what you like. It can additionally generate mouse purrs. You also can either have it overlay the entire desktop windows and all or desktop background only. Make sure to pay attention while installing, as the default language is set to German, so you'll need to change it to English - unless, of course, German is your language.
OK.It's.Raining.Men are meant to be a fun theme to add some movement to your desktop and provide a little amusement with all those trailing raindrops left behind your mouse pointer - still trying to write MajorGeeks in raindrops.
