This is an example of the “matrix rain” code when deployed.
login-image hack
The image files for the login page are located at wp-admin/images/ of your installation, and named login-bkg-bottom.gif, and login-bkg-top.gif
Copy the files from the server, and edit them in photoshop or whatever image editing software you like. Then reload them to the server using the original file names stated above. Keeping the names the same means there is no need to hack the wp-login.php file.
This definitely works for mu, probably works for the stand-alone version as well.
Dust-317 flickr tweak
The file to edit is located at themes/dust-317/left-sidebar.php of your installation.
Line 11 of assigns the flickr user id (this is NOT the same thing as your flickr login id, see below). Replace the string 75017260@N00 with your own string.
You can find the string you want by logging into your flickr account, clicking on the link that says “you” or “your photos”, and then looking at the address line of the URL: www.flickr.com/photos/”yourStringIsHere”
my string is 22879692@N04
