For Windows users, this IS easy, just email Microsoft and they send you a picture of your desktop back since they are always watching what you do on your computer. (OK, so really, you just hit a few keys and your PC will snap a picture of it).
With a Mac running OS X, I have been unable to find an easy solution. Everything I tried just produced a file of the background picture without the icons, etc. So I resorted to taking a picture of it with a camera. After about ten tries, here's the result:
Most of the applications I use are on the tool bar at the bottom (called the "dock" in Apple-ese). It disappears when the cursor is not over it, so it keeps the desktop pretty "clean".
For pictures, I like out of doors shots, mostly ones I've taken. Past ones have included airplanes, Kashima Jingu shrine, and the view from Taveuni Estates, Fiji. This one of a newly planted rice field down the hill from our home is one I took last year.
Who shall I tag? No one. I'm feeling compassionate today.
UPDATE: Thanks to Don Snabulus I know how to do this without wasting a lot of time fooling around with a camera. Much better, and easier. Thanks, Don!
Actually this could be useful knowledge, so this exercise wasn't a total waste of time.
