TuneCenter - Griffin Technology does for your iPod what Front Row does for iTunes and iMovie. It displays playlists and tune info on a the TV screeen. Works with a remote. Getting the Playlist to the screen seems magical to me; I assume the TuneCenter has an embedded operating system but a quick search didn't turn up any leads.
This could be very helpful for visually impaired persons. A cheap compact LCD TV would be much more readable for many persons than the iPod's built-in display. The remote sounds a bit complex however.
