How can I create my own ubuntu theme? [duplicate]
Solution 1:
The easiest way would be to go to /usr/share/themes/, copy the folder of your favorite theme, and start editing/replacing the images and the colors in the configuration files :p
If you'd rather start from scratch, this seems like a good guide: http://orford.org/gtk/
But notice that this guide is for Gtk2, and Ubuntu 11.10 will use Gtk3 ;)
