Poetry Generator: The N+7 Procedure

The N+7 procedure, invented by Jean Lescure of Oulipo (Ouvroir de Littérature Potentielle: Workshop of Potential Literature), involves replacing each noun in a text with the seventh one following it in a dictionary.
In this Poetry Generator you you can enter a text and 15 alternative texts will be generated, from N+1, which replaces each noun with the next one in the dictionary, to N+15, which takes the 15th noun following.
