Here's the link to the WM7 theme at xda:

The theme installs CHome Editor for adjusting the number and order of panels on the home screen, as well as Titanium weather. There is an issue with the weather not displaying properly, but there is a fix in the thread (the fix is basically a new .cpr file which overwrites the initial one).
The panels I had in the screen shot were (in order):
CMyPhotos
CMusic
CVoicemail
CPhone
CClock
CText
CEmail
CCalendar
Titaniumweather
My current layout, which I prefer is as follows:
Titaniumweather
CMusic
CClock
CHome
ATFavePeople
CCalendar
The background is called "Windows_7," and I picked it up from zedge.net Thetaksbar is the Dusk taskbar, made by the same person who did the lockscreen I linked to in another thread - the taskbar and lockscreen can be found here:

I used dusk_6.5_lockscreen_v3.0 and dusk_6.5_wm_21869_taskbar_icons
