GNOME Shell Themes
As a follow up to my previous post about customizing your GNOME Shell, here are a few themes I had recently come across. http://www.omgubuntu.co.uk/2011/10/five-pretty-awesome-gnome-shell-themes/ (opens in a new window). Other than smooth inset, which has been doing the rounds on the internet since GNOME 3 first arrived, the other themes look pretty new to me.
Have fun customizing!
