Saw this great Wallpaper tutorial on Psdtuts.com by Collis for PS and i really liked the outcome, i have re-created it with Gimp using different techniques to achieve the same effect.
even though this original wallpaper was inspired by macs wallpaper i added a touch of Ubuntu logo,lately Ubuntu has really caught my attention to the extent I'm considering buying a Dell laptop Inspiron Notebook 1420 N with pre-installed Ubuntu on it and best of all its only $749 :).
