The credit goes to the people that have enough skill and creativity to create these gorgeous things .
BTW AWN is a very usable piece of software, but it was the default look that kept me away from it. I even asked you how to make it look better one day but it still didn't make me download the thing. Then I saw the screenshot with AWN set up to look exactly like the Mac OS X 10.5 dock so I decided to give it a try - it's awesome. And thank you for the comment .
To be honest, mate, I didn't download anything to it either . You just have to go to the gconf-editor -> apps -> avant-window-navigator -> bar, set the bar_angle to 45 and icon_offset to 18. Then play with the colors and stuff and enjoy .
