If you feel that the default login screen for your Hackintosh is too boring, you can easily replace the background image of the login screen by using
Loginox (Free). Loginox is a free app that allows you to change the background and logo of the login screen in Mac OS X. This isn't a Hackintosh-specific tip; Loginox will work on any Mac running either Mac OS X Snow Leopard or Lion, and it can use any JPG or PNG image of your choice.
The user interface is simple and straightforward; drag any image into the box on the right, and it will replace the current background image of your Hackintosh's login screen. You can reset it back to the default image at any time.
Loginox works automatically, so you don't even have to log out to apply the changes (though of course, you will to log out to view the results).
Besides changing the background image, you can also replace the default gray apple logo on the login screen, if you'd rather use your own custom image.
I personally recommend replacing the login screen background with your desktop wallpaper. You can find the default wallpapers for Mac OS X in
/Library/Desktop Pictures . Of course, the choice is completely up to you.
Alternatively, instead of using Loginox, you could
replace the login screen of your Hackintosh manually. This process requires a lot more involvement (and some basic image editing skills), but it's great for anybody who would rather do it themselves.
