I’ve switched my desktop over to Xubuntu 12.04 and I’m loving it. It’s lightweight, fast, and very easy to configure. (Even though I do very little to configure my machine anyway.)
I was originally going to make a wallpaper (I still may), but decided a quick promotional piece for the next Xubuntu would be more fun. BTW, the next Xubuntu will be codenamed Roaring Ringtail, and the mascot for XFCE is a mouse.
Made in Inkscape, except for the background which was done in the Gimp.
