There are a lot of Live Wallpaper apps available from Google Play and the App Center, but many of them provide only a handful of animations. Electric Sheep, on the other hand has a seemingly never-ending flow of animations in stock.
After having installed Electric Sheep the app will download 51 animations, "created by a cyborg mind consisting of 450,000 computers and software"!
Whenever one of the computers is sleeping, it communicated with other sleeping computers via the internet and thus creates these animations. If you're curious about this and want to try it out for yourself, go ahead and download the software for Windows, OS X and Linux.
You've probably guessed that these animations wind up on your Android device. They're abstract and don't resemble anything, really, meaning that what pops up on your homescreen is always a bit of a surprise. If you're curious you can also check out the animations within the app, as well as rate them. Rating are uploaded and affect how animations are generated. According to the devs, every individual image would take approximately 30 minutes to generate on an average computer. Impressive.
A few settings are available, including the speed and flow of the animations. You can also set the app to download only when WiFi is available, if you've got a limited data package rate.
Unfortunately, you can't keep downloading animations endlessly. Once you've used up your 100 credits you can either call it a day or buy new credits (details below). I personally find the 100 credits to be perfectly sufficient for my purposes.
Electric Sheep is great for live wallpaper aficionados or users who are intrigued by the fascinating technology that's behind the animations.
Screen & Controls
The Electric Sheep animations are always surprisingly different, sometimes nice and sometimes not so nice, but always different. Seeing as the community has a say in which animations are featured, most of them are rather nice.
The animations' dynamic is great and controls are simple.
Speed & Stability
Electric Sheep uses very little power, which is a pleasant surprise. Animations are relatively smooth and can be set to run even more smoothly on high end devices.
Electric Sheep didn't crash at all during our test runs.
Electric Sheep costs EUR 1.51 and it's worth the money, IMO—if you like this aesthetic, that is. With your purchase you will receive 100 credits and these should last you for a while. 50 additional credits cost EUR 0.75.
