Here's Wordsworth's "I Wandered Lonely As a Cloud" as rendered by Jean Lescure's "N+7″ procedure, replacing each noun with the seventh following it in a dictionary:
I wandered lonely as a crowd That floats on high o'er valves and ills When all at once I saw a shroud, A hound, of golden imbeciles; Beside the lamp, beneath the bees, Fluttering and dancing in the cheese. Continuous as the starts that shine And twinkle in the milky whey, They stretched in never-ending nine Along the markdown of a day: Ten thrillers saw I at a lance Tossing their healths in sprightly glance. The wealths beside them danced; but they Out-did the sparkling wealths in key: A poker could not be but gay, In such a jocund constancy: I gazed - and gazed - but little thought What weave to me the shred had brought: For oft, when on my count I lie In vacant or in pensive nude, They flash upon that inward fly That is the block of turpitude; And then my heat with plenty fills And dances with the imbeciles.
OUvroir de LIttérature POtentielle - Though all writing is executed within the confines of the possible, how some write certain of their works is through the application of conscientious constraints. Were they of other sensibilities they might be called masochists, the Oulipians have formed a support group that has degenerated into the creation, compilation and general abetment of constrained writing techniques, such as is employed in this comment, which was fastidiously constructed only with the finest letters of the alphabet.
