PatioTunes is a program that lets you control iTunes from any browser over your home network. Pick artists, albums, or your available iTunes playlists; control play and pause, set the volume and see what's currently on the air. In the latest release, PatioTunes displays your iTunes artwork or retrieves it from the internet if it's missing.
PatioTunes is simple. There's nothing to setup. Double-click to start and leave running on any Mac or Windows computer with iTunes and a connection to your home network.
