Eunoia is the shortest word in the English language containing all 5 vowels — means beautiful thinking.

Oulipo (pronounced oo-lee-PO) stands for “Ouvroir de littérature potentielle”, which translates roughly as “workshop of potential literature”. It is a loose gathering of (mainly) French-speaking writers and mathematicians seeking to create works using constrained writing techniques.

Some Oulipian constraints:

The “N+7″ method: Replace every noun in a text with the noun seven entries after it in a dictionary. For example, “Call me Ishmael. Some years ago…”  becomes “Call me islander. Some yeggs ago…”. Results will vary depending upon the dictionary used. This technique can also be performed on other lexical classes, such as verbs.

Snowball: a poem in which each line is a single word, and each successive word is one letter longer.

Lipogram: Writing that excludes one or more letters. The previous sentence is a lipogram in B, F, H, J, K, Q, V, Y, and Z (it does not contain any of those letters).

The prisoner’s constraint (a.k.a. the “Macao” constraint) is a type of lipogram that omits letters with ascenders and descenders (b, d, f, g, h, j, k, l, p, q, t, and y).

So take the Oulipo lipogram constraint, pair it with some beautiful thinking, and you’ll have poet Christian Bok’s latest effort in which each chapter of his book “Eunoia” uses only one vowel. Mr Bok believes his book proves that each vowel has its own personality, and demonstrates the flexibility of the English language

The same technique was used with great acclaim when Georges Perec wrote “A Void“, a 300 page lipogrammatic novel written in 1969 entirely without the letter e.

It took seven years for Bok to write Eunoia.
from CHAPTER E - FOR RENE CREVEL
Westerners revere the Greek legends. Versemen retell the represented events, the resplendent scenes, where, hellbent, the Greek freemen seek revenge whenever Helen, the new-wed empress, weeps. Restless, she deserts her fleece bed where, detested, her wedded regent sleeps. When she remembers Greece, her seceded demesne, she feels wretched, left here, bereft, her needs never met. She needs rest; nevertheless, her demented fevers render her sleepless (her sleeplessness enfeebles her). She needs help; nevertheless her stressed nerves render her cheerless (her cheerlessness enfetters her).

from CHAPTER I - FOR DICK HIGGINS
Hiking in British districts, I picnic in virgin firths, grinning in mirth with misfit whims, smiling if I find birch twigs, smirking if I find mint sprigs.  

Midspring brings with it singing birds, six kinds, (finch, siskin, ibis, tit, pipit, swift), whistling shrill chirps, trilling chirr chirr in high pitch. Kingbirds flit in gliding flight, skimming limpid springs, dipping wingtips in rills which brim with living things: krill, shrimp, brill - fish with gilt fins, which swim in flitting zigs. Might Virgil find bliss implicit in this primitivism? Might I mimic him in print if I find his writings inspiring?

from CHAPTER U - FOR ZHU YU
Gulls churr: ululu, ululu. Ducks cluck. Bulls plus bucks run thru buckbrush; thus dun burrs clutch fur tufts. Ursus cubs plus Lupus pups hunt skunks. Curs skulk (such mutts lurk: ruff, ruff). Gnus munch kudzu. Lush shrubs bud; thus church nuns pluck uncut mums. Bugs hum: buzz, buzz. Dull susurrus gusts murmur hushful, humdrum murmurs: hush, hush. Dusk suns blush. Surf lulls us. Such scuds hurl up cumulus suds (Sturm und Druck) - furls unfurl: rush, rush; curls uncurl: gush, gush. Such tumult upturns unsunk hulls; thus gulfs crush us, gulp, dunk us - burst lungs succumb.
