i'm using a home screen replacement called dx top, it adds a dock at the bottom which you can place apps into (4 of them) as well as 4 home screens and a bunch of other stuff. there's a thread about it in the apps section if you want to learn more.
it also adds a screen capture function to the phone which is how i got the screen shot. easiest way to do it so far, and i love the extra functionality of the app.
and the weather clock is called "beautiful widgets"
