This is a GNOME Shell theme based on the Ubuntu Lucid theme called Ambiance.
Curved panel and various elements.
Ubuntu Empathy like chat theme for the chat area.
Transitions and hover and click states.
My "recent items" seem to be broken, so it may not be themed properly because I cannot do this currently.
This theme is based on GNOME Shell 2.31.4.
Backup your /usr/share/gnome-shell/theme directory.
Extract the theme.zip and copy the theme directory to /usr/share/gnome-shell/
Restart GNOME Shell by Alt, F2, then type r and press enter.
