We don't usually feature live wallpapers on the XDA Portal unless they are somewhat innovative and offer some kind of improvement over the vast sea of wallpaper apps currently available. More often than not, these apps will either make the current wallpaper on our screen come to life, such as those offering a parallax effect, or they may even be interactive such as the classic Nexus live wallpaper. There are even a few apps out there that turn your device into your handheld picture slideshow. All these are fine examples of things that are out there. But what about when you can't decide on a single picture to set as your wallpaper? Sure, if you are a master with Photoshop or GIMP, you can create your own collage. But what if you are not--or you simply don't have the time? If this applies to you, then you might want to check out what XDA Senior Member jruesga has in store.

PhotoPhase is a live wallpaper app that is quite unlike most slideshow wallpaper apps. This app allows you to define several areas of your home screen wallpaper, and it lets you change the size and position of each section. Once you have that squared away, the app allows you to choose a picture folder or you can define a subset from your gallery. After you are done, it is time for you to play with transitions, effects, and touch actions. Each individual image can be treated as a separate entity, which means that they can all have a different transition effect, along with other picture effects.

The app is completely open source and, considering what it gives you, it is relatively light on system resources. However, this last item will vary depending on the size and quality of the images being used for wallpaper. The app is featured packed, but the dev still would like to hear your thoughts on improving it and making it better. Suggestions are welcome and as usual, if you have bugs to report, make sure you provide all the necessary details (and a logcat would be nice as well). You can find more information in the PhotoPhase application thread.
