Since Lion launched we’ve covered a few hacks that describe how you can change Mission Control’s and Dashboard’s background, as well as how to change the background of folders in Launchpad - but most of them have required some level of manual file editing and replacement. Fortunately, developer Moritz Wette has made it a whole lot simpler to customize the look of Lion with his app, Lion Designer.

Lion Designer lets you customize the Mission Control, Dashboard, Launchpad folder and the login screen background as well as the Launchpad folder icon. The developer suggests using PNG images that are at the resolution of your screen or are images that can tile - otherwise you’ll end up with something that looks messy. Though if you don’t like how something looks after you’ve changed it, or something has gone wrong, you can easily click the reset button and Lion Designer will return it to the stock look. I gave the app a quick spin and found it worked fine, with my Dashboard now displaying the familiar and soothing linen pattern. Lion Designer is available for free, but be sure to send over a small donation to Wette if you find the app useful to you.

If you’re looking for some other apps to tweak and customise OS X Lion, have a look at these apps that we have covered in the past:

Lion Tweaks - Lets you turn various features in Lion on or off, examples include removing the system Window animation, disable spelling correction, enable permanent scrollbars and many more.

Launchpad-Control - Hide any app you want from being displayed in Launchpad

LaunchpadCleaner 2 - Also allows you to hide apps from Launchpad as well as some more in-depth features.
