"wonder how many people - especially this audience - really care about what's on their desktop."
I do. The duller, the better. Uniform gray is my preferred background (not too bright red on production systems or when logged in as administrator).
Pictures I liked had 'dull' parts in regions where icons tend to show up. An option to reduce (color) contrast would be a nice feature, especially if it were to have some smarts depending on the picture and what icons are on the desktop.
Have you seen the Android wallpaper app Muzei [0] ? It dims and blurs the image, and launching the app or double tapping the wallpaper itself brightens and focuses the picture momentarily. No idea if that is possible on OS X though.
Difficult to implement something like that on OSX without a resource-intensive overlay. As it is, Artful takes advantage of the built-in NSWorkspace API to change the wallpaper, which only causes activity on download and change of the image.
