I'm considering buying one of those commercial style tv's that can be kept on for long periods of time, so I can put my entire plex library on shuffle in the background while I do other things throughout the day. But I'd prefer if the "shuffle" was a little more customizable than what plex offers at the moment. Are there any projects that attempt to mimic the old-school channel-style setup from before the internet? i feel like such a setup would be ideal, since I could create several channels for different styles of media, but still have the randomness.
