Mine is just a stock Apple background at the moment.
If anyone is interested in some nice Disney wallpapers, I have a few of my photos up for download on my site. Just let me know if you use one! I wanna see how it looks! :wave: http://wallpaper.webcookie.net
Mine's a picture I took in December in Epcot. It's taken in the WS of the park looking towards SSE with the monorail approaching it and the reflection of it in the water.
Well, I had that one until I had to redo my computer a couple days ago, right now it's a picture of the fountain as water is shooting up really high with SSE behind it.
My desktop is a variation of MK's castle that I downloaded off of Disney Experience. I highly recommend you visit the site. It's a great site to pick up wallpaper, fonts, and other Disney themed stuff for the computer.
