Edit for my answer is appreciated. I don't think it's clear.
Edit : More Complete Solution !
<p>Google "Mac OS X hints" and "10.4: See multiple feeds over time in RSS screen saver ".</p>
<p>One poster made a perl script using rss screen saver that enables rotation.</p>
<p>Feed43 allows you to convert any web page in rss</p>
<p>P.S.: Vote up if you think it's complete !</p>
Solution : Use something like this program : WindowBox
There is a Screensaver integrated into Mac OS X called RSS Screensaver. It should be pre-installed on any Mac OS X computer.
Here is an helpful article by LifeHacker : Google "lifehacker" and "make-your-idle-screen-useful-with-these-fun-functional" together.
Life Hacker and TechNet have many useful guides.
If you really need a screensaver that will allow you to add any site, you might use a few alternative sites like alternativeto. They allow you to find similar products. A well constructed search on the alternative sites or on google may give the result you want.
Here are additional resources for thought taken from : http://www.hackmac.org/forum/topic/328-facebook-notifications-on-as-wallpaper/
and
an interesting book page : http://books.google.ca/books?id=vrGbAgAAQBAJ&pg=PA127&lpg=PA127&dq=hack+rss+screensaver&source=bl&ots=zXBBPh-sxG&sig=RSzZ85jo9RmuY3toWVR5URLTatM&hl=en&sa=X&ei=fnvkU-CGKJCdyASK9IHQAw&ved=0CGsQ6AEwCA#v=onepage&q=hack%20rss%20screensaver&f=false
You can use services like Feed43 to enable rss to sites that don't have any. You would use afterwards this on your rss screensaver on your Mac Os X. If it doesn't help, at least you'll get a much wider choice. :)
The Book posts a script snippet allowing one user to change his desktop images on mac with websites. It is a Perl Script so it is easy to pick up. I am too lazy to post it. Further google search with terms mac + perl + screensaver would definitively lead to the results you want !
I hope the question is solved !
P.s. : I searched like a pro. Congratulates myself.
As I understand, the problem consists in those steps :
- Accessing the sites
- Displaying the sites
Add the Sites to the Screen Saver.
Refresh (Screensaver every 5 minutes (?))
You want to use Applications but Code can be fine.
Google Search Suggestions :
- how to set a screensaver as a site --> Basic Research
- view news with screensaver --> Code Snippets. Possibility to find what your search for.
- site:superuser... [Your Question]
- Alternatives + Screensaver program for suggestions.
Fine Programs :
web-page-screensaver
Live Screensaver Creator
Web Saver
There's a Few Programs like WineBottler that allows you to run other OS programs in Macs. I really like those programs. I should start a download party another time.
P.S. : Download Party --> Acquire many utilities in one day. Test them. Uninstall 1/3 to 2/3 of them. You'll end up with someone you like and that is very useful. Enjoy !

Code Master :
If you want to build code, you would need to follow those steps :
Access the sites.
Run a Background Application that takes over your screensaver to display websites.
**OR**
Convert the Websites into images and put as screensaver.
Conversion : You can use the output of a command as input. There are few languages that may help. Batch-Bash or Visual Basic can handle the task easily.
Note : I am sorry if I couldn't forward you to certain programs. The Choice seems to be wide. Having an example of your old screensaver or making a table of features you expect could help. I am not using any of those programs. I can't suggest something I never used.
