I have this ‘strange’ hobby of creating Desktop backgrounds across a variety of topics and subjects, however most of them are sports related. You can see much of my collection at my website: http://www.sgclark.com/wallpapers (click through the images on that landing page to see the full collections for each topic/sport/league, etc.)

Having unique and ever changing Desktop backgrounds is a big deal to me…it keeps the computer fresh and always different. I love the fact that Mac’s enable you to rotate desktop background at any variety of time segments, from every 5 seconds to every day. And on top of that, as many of you probably know, you can select the folder that you want to ‘source’ your background images from. You can go to System Preferences > Desktop & Screen Saver to see all the settings.
Since I use an iMac Desktop and a MacBook Air, I wanted to have the same set of Desktop backgrounds decorate each of these computers (and any other Mac computer that I may use).
So what I do is I put all of my Desktop Backgrounds into a Dropbox folder. I then install Dropbox on each of my Mac computers, and after it has synced to each (and all) of the devices, I then set up each computer to point to the same Dropbox folder that houses my Desktop Backgrounds.
By doing this, each of my computers source from the same set of Desktop Backgrounds that rotate (in my case) every 5 minutes. So even though I’m using different computers, they feel similar because the Desktop backgrounds are the same.
I wrote up the specific steps a few years ago on my site.
