10.0 Cheetah & 10.1 Puma

The first two releases of Mac OS X shared the same wallpaper. The sweeping blue arcs and curves helped set the tone of the new Aqua interface.

10.2 Jaguar

Jaguar took the same Aqua-inspired theme but added some depth and motion to things. In my head, the trails streaking across the screen were from a set of comets.

10.4 Tiger

Many consider Tiger to be the best “classic” version of Mac OS X. While that may or may not be true, it is my favorite Aqua-inspired wallpaper.

10.5 Leopard

Complete with a revised, unified user interface and shiny new Dock, 10.5 broke the Aqua mold. As such, Leopard was the first version of OS X to break from the Aqua-themed wallpaper. It ushered in the “space era” of OS X wallpapers, which was used heavily in the new Time Machine interface as well.

10.8 Mountain Lion

Just like Snow Leopard before it, with Mountain Lion, Apple opted to clean up and revise the existing theme as opposed to changing directions for what would be a less-impactful release of OS X.
