At almost 11 MB, Weather Live Paper, a live wallpaper about the weather, is sumo-sized, but it doesn't deliver.
I had tried to setup the app, both by entering name of my city directly (How many "San Francisco" can there be in the world?), and to use my location directly. I got nothing. Weather always say ????????.
Background scrolls continuously which is kinda cool, and the words shift a bit, but if the weather doesn't work, then it's not a weather live paper, is it?
You may have better luck than I do. However, Go Weather works and is much better.
Rating: Try it, but you'll probably ski pit
