What if I want more than one RSS feed in my Tiger screensaver?

A few weeks ago I was bitching moaning whining to C.K. about how no matter how many and which RSS feeds I bookmarked in Safari, I couldn't get them to show up in the RSS feed "pick-list" in Tiger's screensaver preference pane. I was running an earlier developer build that obviously was slightly broken in this respect and it had me baffled. Of course now the feature works just fine and C.K. got the satisfaction of showing the world how easy it is to add your own feeds before I had a chance to.

Since you're so smart, C.K., why don't you tell me how I can rotate more than one feed in Tiger's screensaver?
