Ubuntu(for all versions – 10.04(Lucid Lynx)/10.10(Maverick Meerkat) or the upcoming version 11.04(Natty Narwhal) with classic desktop selected at login menu,because Ubuntu 11.04 uses Unity desktop, by default) uses GNOME Desktop as the default Window Manager.
GNOME is the most popular(of course it’s free and open source) desktop for Linux Distributions, probably due to its(GNOME) flexibility and the desktop components (Themes, Icons, GDM, Window Managers provided by Compiz, Emerald, Metacity etc.) available freely on the Internet (so you can customize the desktop as you want, the Only limit is your Imagination Power).
There are lot of free, Awesome and cool GNOME themes available on the Web, so lets(I change/rotate my theme at least once a week) try something new,something different, because we are Humans, and of course – Linux users, so picky (because we have always a lot of options available for a single task). Since I am listing the themes for gnome desktop so most of the themes will not only work on Ubuntu but also on other Linux Distros,which uses GNOME as their default desktop e.g Linux Mint, Fedora, Debian etc. Finally here is my all time favorite(and great) collection of 10 cool Ubuntu Themes(I assume you are using GNOME Desktop) –
