From Wikipedia :
OULIPO: short for French Ouvroir de Littérature Potentielle; roughly translated: “workshop of potential literature” is a loose gathering of (mainly) French-speaking writers and mathematicians who seek to create works using constrained writing techniques. It was founded in 1960 by Raymond Queneau and François Le Lionnais. The group defines the term “Littérature Potentielle” as: “the seeking of new structures and patterns which may be used by writers in any way they enjoy.”
Using this kind of “potential literature”, Professor Jaime Correa created and submitted two pieces of artistic writing for publication in a book titled “Dear Architecture.” His two “Dear Architecture” pieces came out of an ideas competition hosted by Blank Space; it challenged designers to explore the use of a letter format as the focus for each piece while confronting issues facing the architecture profession through drawings. Correa said that both drawings could be classified in the same category of those paintings of “Metaphysical School” made famous by Giorgio de Chirico and Carlo Carra, in Italy.
His first drawing was focused on the letter “O”. He explained, “The drawing understands the letter “O” as a container of space, a letter which, unfortunately, is not included in the word ARCHITECTURE. My written message, addressed to DEAR ARCHITECTURE and missing the letter “O”, can be read all at once or by single colors. The whole argument focuses on the idea that American architecture will not be able to realize the power of space until its own name begins holding specific references to the most important letter in the life of an architect. The image is a choreographed game of objects containing the letter O in plan, section, and elevation – even the window is a letter “O”.
Correa’s second piece, titled “Sick Joke,” was selected for publication in the book. He added, “It is a call to order in three languages – attempting to call the reader’s attention to the global conditions of our contemporary times and to the state of crisis of our profession”; he said. “It simply states that architecture as a profession is no longer a civic art but an infamous joke. The drawing shows a building in section with empty rooms, objects of desire, and windows through which you can see famous architectural cartoons – cartoons which make fun of architects or famous pieces of architecture.”
