That's about the gist of it. It's going to be called "The secret of Vault 20" or something to that effect. It includes a Vault whose social experiment was to man a nuclear bomb shelter with only bronies, whose only source of media or knowledge in some way includes MLP: FiM. It explores the effects this would have on people, who for generations would know only ponies, how it would affect their culture and how they would react when finally exposed to the post-apocalyptic world 200 years later. I'd like to use the picture on some things (posters/banners/tradingcards) in the vault.
