“The deep space relay station near Tau Centauri hasn’t been visited in thousands of years. It has been cut off from its surrounding universe by a nova - no information about when or if a life form will arrive again. Its computer, however, is still performing routine maintenance, including onboard dataset maintenance. Currently, for the past 600 years, it has developed an affection towards specific data, musical works by a human composer from the pre-FTL years, and so it adjusts the light apertures to play his music to the vegetation on deck.”
P.S.: It’s a perfect loop, but I’m not sure where best to publish so it would support long loops like that.
