This is one of those things that Google would probably give me the answer if I could think of the right question.
I want to create an information screen, similar to the kind of things you see in railway stations etc, maybe showing a live TV feed in one area, some headlines coming from an RSS feed, a slideshow of images in another area, etc.
Ideally I'd like something that runs from live-CD, with configuration on a USB stick, so that restarting the PC just restarts the system without risking any corruption.
Any suggestions, whether to what I should use or at least what I should search for?
