Change Apple Logo on your Mac in Lion

On Mac OS X Lion, you can change the Apple logo to your own logo.  Let's do that now.  Here's a BB logo we want to use:

Grab the file and copy it to your system (let's say /Users/YOUR_USER_NAME/Downloads/BBRocks_256x256.png).

Then open Terminal and type the following to backup the original file:

sudo cp /System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/A/Frameworks/LoginUICore.framework/Versions/A/Resources/appleLinen.png ~/Desktop/

And then this to copy over the Apple logo with your new logo:

sudo cp /Users/YOUR_USER_NAME/Downloads/BBRocks_256x256.png /System/Library/PrivateFrameworks/LoginUIKit.framework/Versions/A/Frameworks/LoginUICore.framework/Versions/A/Resources/appleLinen.png

Now your login window should look like something like this:
