I've been wanting to start this thread for quite while now and here it is......
A bit of background first....I've been testing Gnome-Shell for almost 2 years now and like using it (maybe I'm a bit STRANGE


In Experimental you can install the gnome3-session and gnome-shell--it's running quite stable right now (and I would "guess" that it will stay that way because of the release date for Gnome3)
***After you set up you will need to create a NEW user...else the fonts and several parts of the desktop will default to 58px--not a very pretty sight


As far as I know this is no longer needed...can someone check please?

This is the "normal" desktop view---I am using AWN because I still need a dock/panel to access stuff quickly. I'm very sure when Gnome3 is released there will be quite a bit of hacking on it--all the code is pretty easy to change, so the functionality will be a "plug-in" most likely in the near future. The bottom of the screen has a hiding notice area--hotspot the right lower corner to unhide.
This is the "Windows" overlay...you hit the hotspot in the upper left corner to bring up Overlay...it currently has 2 modes. you can sticky a favorite app in the side dock or choose one of the running apps here. There is a hotspot on the right side to add/subtract desktops in this mode also. Notice the rather basic System-Preference control panel (lower-right app)
This is the "Applications" overlay. As you can see the full Apps list comes up by default and you can sort the menu by types on the right side. Both Overlay modes have a Search box at the upper right corner. You can see the Notices at the bottom (unhidden) in both the Overlay modes.
You can run Gnome3 without running the Shell...just choose the normal Gnome session on login--that will run a UN-accelerated desktop with low "needs"

I will be adding/modifying this thread on a more/less constant basis as things change....be sure and return to the first page to see the updates as they are posted!!!!!
Update 5/14/11
I've been a bit lax on updating the front page---Theming is now very possible in Gnome-Shell.
1> Gnome-Tweak Tool can change your Icon-set, GTK3 theme & several other "Look & Feel" parts of the Interface.
2> Gnome-Shell Theme Selector is being actively works on--See pg 3 for comments & info. Main Information pg: http://blog.fpmurphy.com/2011/04/gnome- ... eview.html
I have posted install info for both on pg 3.........
Update 8/28/2011
Updated the pictures to reflect how Gnome-Shell can look at present.
