Linux software or distribution for running a kiosk-type slideshow screen? You've seen them in doctors offices and sometimes restaurants. They're typically used for advertisements. I've been tasked with creating a screen that can show variable information with little to no user interaction, but I don't want to reinvent the wheel.

Is there some software that will easily allow me to hook up a Linux box to a screen, is easy to update remotely, and will cycle through a variety of media in a fullscreen display?

I'd like to potentially display various picture formats, HTML, perhaps videos, RSS feeds, etc.

Surely someone has done the legwork on this already? If not, I considered creating a website with meta-refreshes between each page, then loading a full-screen browser on the kiosk computer and pointing it to the site. This would allow me to handle the updates on the web server.
