Android Wallpaper Project

I currently have a live wallpaper that acts like a somewhat like a game. There is two characters who walk around fighting each other with AI or the help of the user. The scene consist of a street and a background of buildings. ----------------------------------------------------------------------------------------------- I am looking to give the background a bit more functionality by doing the following: Replacing the color of the sky to the users current time of day, it doesn't have to be complex, just something that gives a close effect. The scene is not slightly modified, so the boundaries have changed for both x and y, so the characters should not step out or walk on buildings. The scene modification includes the addition of "billboard" graphics on both ends of the scene. On the paid version, These billboards will cycle through the users photographs and display them with some transition effect between them. On the free version, only one will cycle through users photographs, the other will display an ad from the adsence that i will link to my account. The ad doesn't have to take up the whole space as large as the size of thee billboard. The user will be able to click on this ad to take them there. These billboards might be at an angle, depending on the size and limitations. There needs to be options to choose which album the user can see, or to turn on/off ads. (on the paid only) Please message me with questions.
