Everything started with Cheetah. Then we had Puma. Then we had Jaguar. Then we had Panther. We're now using Tiger. But your PDA deserves more, than just Ozone Update - here comes Leopard.

Leopard 1.0 for Wisbar Advance Desktop 0.3+ by KTamas (ktamas.deviantart.com) 
Theme includes two wallpapers, and the icons you can see on the screenshots. You can find three theme files in the zip file: the default.skin includes all icons and plugins in the theme, the default_noplugins.skin has only the icons and the default_dockonly.skin has only the dock and the four virtual pages. Copy the skin file you want to the \Themes\Desktop\default\ folder as default.skin. Also, please copy the "OSX" folder to \ (root) and Lucida Grande.ttf to \Windows\Fonts.
