RSS Feeds and the RSS Visualizer Mac screensaver:

Bring up the RSS feed from your favourite source as a screensaver on an (OS 10.4) Mac. Nifty!

I often have this screensaver set to the BBC International Headlines RSS feed, but I only just figured out how to customize this to more than the default set of RSS feeds supplied by Apple within Safari...

You need to make sure your desired RSS feed's URL is saved by Safari before you can get this to work.

1. a. Launch Safari and navigate to your desired source.
b. Check to see if they have an RSS feed (should be on the front page if they are worth their web-savvy salt, and Safari will display an RSS button in the address bar if it can detect it). RSS feeds are sometimes called XML feeds.
c. Click on the RSS button or link link to display the RSS feed within Safari. You should see a list of titles and brief excerpts of postings.
d. Bookmark this page (the RSS feed, and NOT the website itself - you should see an URL ending with .xml).
e. Close all Bookmark management related windows! This ensures you are actually saving the URL within Safari's Bookmarks.

2. a. Launch the System Preferences app from the Apple menu
b. Click on the "Desktop & Screen Saver" icon.
c. Click on "Screen Saver"
d. In the Screen Savers list, select "RSS Visualizer"
e. click the "Options..." button
f. select your desired RSS feed from the displayed list of all your Safari RSS feeds, and click the "Done" button

Sigh. Don't display your own blog RSS. That's just plain vanity. Give your family grief for not doing it.

One feed that gets me laughing (caution, may be mildly offensive to some): The Onion - weekly
