This is my very first GTK-theme. It tries to imitate OSX Tiger operating system's Aqua theme. There are some differences, because GTK sets some limits what you can do and what not.
Theme uses some graphics from Glossy P theme.
This theme uses pixbuf engine so in Ubuntu you'll need to install gtk2-engines-pixbuf package.
I have written more about OSX imitating on my website www.taimila.com.
