Apple earlier today released the Mac OS X Lion Beta Preview 3 to developers. The latest preview build of the upcoming Mac operating system features a good number of changes: A new login screen and a new animation when logging into the computer, an updated finders toolbar, updated scrollbars that change color depending on background, a Mission Control app, new iCal Reminders, and a bevy of new wallpapers

Included in the new wallpaper pack is, of course, one of a lion, as well as other wallpaper-y images like misty forests, lakes, floating leaves, a beach, an eagle flying by a waterfall, a forest with a pinkish tint, and various flowers. Check 'em out.
