This is my linen theme for Slim, inspired by the osx lion login theme. its optimized for 1440x900
This theme has three versions:
Arch (rename a-background.png to background.png )
elementary (rename e-background.png to background.png )
The preview shows all three logos in action but the actual version has only one logo in the center.
you can also use the backgrounds as wallpapers without Slim
Included is the .xcf source so you can make your own logo for your favorite distro
