Sure Live Wallpaper are cool.
Cooler yet they are when you can get information that's usefulwithout even knowing it.

ParanoPaper shows you which time of the day is by changing theconfiguration of its sky.
It also shows your battery health though the growth of a cutelittle tree.

Of course we want to involve so much more information on thislittle thing. Your altitude, the tides, weather, temperature,alerts, and many others. But these will come with time, until then,enjoy.
