A boy opens a book left on a bench and finds a tower. Inside that tower sits an old man reading in a library that contains every story ever told, watching mythical beasts flicker in and out of existence as he turns pages. Five minutes is all it takes to understand what Borges spent his whole life trying to say: that stories are doors, and every reader is both the keeper and the prisoner of infinite worlds.

A boy and his little sister come across a book someone has left behind on a bench, and their curiosity gets the better of them, so they open it. On one of its pages, a tiny Tower of Bavel takes shape. Peering inside, the pair find an old man seated and reading, with endless books piled all around him. Each time he turns a page, mythical animals appear and then fade away again. The story is told in a single animated special from 1996.
