I seem to be on a Starbase Omicron kick of late. Two in a row, this one is similar in use to the Pipes download from last week. Why conveyor belts? There always seems to be conveyor belts in Sci-Fi movies and games. Virtually every FPS has a level with them and they feature prominently in “Star Wars: Attack of the Clones.”
At any rate, why do you need an excuse? You’re the Game Master!
