We just completed a couple big upgrades to "The Burbs" live wallpaper. It is now Time and Season sensitive. This goes quite a ways towards our goal of re-creating a virtual neighborhood on your Android phone.
Check it out on the Android market and see what you think!
The next focus will probably be on app behaviors. We would like to add dogs chasing cats, birds flying, more sophisticated app behaviors for the villagers/cars. There are many more villagers as well. We started with 10, but actually have around 25 distinct people. We may come up with a more sophisticated way of swapping the people around to create a larger variety.
