Ah, unfortunately, both the icons and desktops are custom made by me, so I don't have any Barça ones. The icons are easy to make, though! I just went to Google, found the images, edited and sized 'em in Photoshop, and then transformed them into icons by using a piece of freeware I found on VersionTracker. It honestly took about five minutes total.
My wife got a hold of the computer and changed the desktop and the layout of the geektool scripts. I just added the calendar with the date in a separate color.
Heres mine for the end of Movember!
Background: attached as well.
Calendar: Dateline
iTunes art: Bowtie
Messenger: Adium
Dock: Various bits and pieces to get it to look like that.
