I take it back... this program is not a crap shoot at all.
It's very reliably buggy to the point of being completely useless.

Do yourself a favor, if you manage to get it to work, save all of the wallpapers you like and then ditch this POS.

This app has some really nice background pictures in it's online library.

The app, however, does have some very annoying problems. I have set this app to "Start at Login" and change images every 10 minutes. Most of the time, the app doesn't show the current image name or the rating sub-menu items. I have to stop and restart the app several times using the preference pane for it to launch properly. It's a crap shoot until it launches properly. I can navigate back and forth between backgrounds even without the name and rating menu items. However, when I click on Previous Background, the image name and rating don't get updated as it continues to show the previous image name and rating details.

Once I to stop Desktoptopia via the System Preference pane, I cannot realunch it without first relaunching the System Preferences app. Clicking on the "Start Desktoptopia" button does nothing.

I hope the developer fixes these problems and keeps expanding the image library.

I LOVE THIS SOFTWARE! And my wife does, too. I highly recommend trying it.

All the images are vetted by the developer and there's a little something for everyone.

What I like best is the sense of expectation and surprise. You never know what the next image will be. That sense of playfulness helps the work day go by faster. (I rotate every 10 minutes.)

Some other reviewers question the cost, but I feel like I get my money's worth every day. Sure, I could spend an hour looking around online for new desktops every week and have the OS cycle through them for me, but who's got that much free time? And it's much more FUN when you don't know what will be coming up next! Seriously!

I'm happy to buy into Desktotopia on the grand floor, because I think it's just going to get better as they increase the quantity and variety of images in rotation. I hope that's where they're putting their development energy right now. (If you're an artist/photographer, you can submit desktops, too!)

I'm in a proxy server environment, and I had to tweak my Mac's network settings to get things rolling, but it works fine now.

Try it. You won't regret it!

Why on earth would anyone spend a twenty on a desktop changer ?

Very 'nice' - 'Computer arts' magazine style wallpapers/desktop pics but twenty bucks ?

Buying desktops is like buying screensavers, a seriously weird phenomena and inexplicable - so I won't try.

Same problem here, the preference pane won't open (actually it does from time to time, but not very predictably...) and I also feel that the wallpaper doesn't change automatically when it's supposed to...
