This is a little demo app that comes with the UI framework. As you can see it's quite touchy and finger-ready. One of the cool things about it is that it compiles and runs on my desktop. I've even installed this app on my n900 and it runs fantastic on even low-powered devices.
Note that MeeGo is still in heavy development, so what you so now probably won't reflect how things will look later on.
The themes are CSS based so it's pretty skinable that way.
