I saw this yesterday and just had to download it and so far I actually really like it. This is a live wallpaper called Pixel Rain and it is full of options and features yet its completely free in the Android Market. I know everything is HD these days and all the apps keep getting updated to work with higher resolution screens and all that jazz, but this retro looking wallpaper just rocks.
From reading reviews everyone seems to enjoy it just as I am. With as many options as the developer provides all free of charge it's worth a look that is for sure. You can change the amount of rain drops, make them multi-colored, change the size and speed of the falling pixel rain drops and more. I like that you can make the rain drops splash or "shatter" on impact but it was a little distracting.
Make sure you check this out and don't forget to thank the developer Shawn Gilleland in the reviews if you like his one and only (and well done) application. For those that love LPW (Live Wallpapers) we also have the secret Galaxy S II LWP you can download here. Or we also covered the TrueBlood Wallpaper a while back. So go ahead and give Pixel Rain a try and let us know what you think.
