<h1>Grafted trees</h1>

<main>

|
‘Grafted trees’ takes quotes about trees from existing works. Each graft is defined by its gardener, who is present with a short biography scraped from Wikipedia. The reader chooses the amount of seasons the graft will grow. A random noun is picked and defined as a 'bud' from which a new branch grows by replacing the word by its definition. The algorithm is inspired by Oulipo's constraint of 'Littérature définitionnelle', invented by Marcel Bénabou in 1966: in a given phrase, one replaces every significant element (noun, adjective, verb, adverb) by one of its definitions in a given dictionary; one reiterates the operation on the newly received phrase, and again.
