+    The Arte of ASCII: Or, An True and Accurate Representation of an
+  Menagerie of Thynges Fabulous and Wonderful in Ye Forme of Character
+
+Abstract
+
+   Ever since Gutenberg discovered and patented ASCII and the
+   corresponding "Courier New" font with its now-famous "ten" point
+   size, artisans and artificers have striven to represent their views
+   of the world in print.
+
+   Similarly, starting from Darwin's discovery of the hippogriff and his
+   subsequent registration of the creature as an International Trade
+   Mark, men (and some women) have struggled to catalog the fabulous
+   variety that is called "nature".
+
+   This document supplies a number of representations of all manner of
+   things (both elemental and hypothetical) supplied by some of our best
+   collectors of curios and delivered in a manner that may well be
+   reused by the cunning document author.

+1.  Introduction
+
+   Once upon a time, in a land far, far away, where princes were
+   available to those who knew how to kiss, and frogs could be picked up
+   by the handful and were sold in brown paper bags at the shop on the
+   corner of your street, there was an impish discovery made by the
+   appropriately named Johannes Gensfleisch zur Laden zum Gutenberg.
+   His name, it turned out, was coincidentally fortuitous for when he
+   uncovered the Gutenberg Press he was able to claim it as his own.
+
+   Amongst Gutenberg's better known discoveries were the ten point font,
+   the Courier New Font (which he is supposed to have found growing in a
+   hedgerow close to his cottage), and the ASCII character set.  All of
+   these have been embraced as comforting and warm blankets by the
+   engineers of the IETF as they embark on expeditions to plot the
+   desolated wastes of the Internet.
+
+   Although the RFC Editor has recently dragged the IETF kicking and
+   screaming into the twentieth century [RFC7990] [RFC7996], there is a
+   yearning among all right-thinking Internet architects to "keep it
+   simple" and to return to the olden days when pigs could be given
+   thrust without anyone taking undue offence [RFC1925].  This document
+   attempts to address that yearning by demonstrating the full wonder of
+   the natural world in vivid two-dimensional representation and a
+   colour palette that would put even the august L. S. Lowry to shame.
+
+   Readers of this document are encouraged to be familiar.
+
+2.  Beasts of the Land
+
+   "Many and wonderful are the beasts of the land" wrote the poet.  And
+   he was right in some ways.
+
+   Of these many beasts, the most fabulous are the Troll and the
+   Unicorn.  Here are reproduced representations of sightings in the
+   field.

+
+2.1.  The Troll
+
+   The troll is an evil beast that frequently appears around the IETF.
+   It feeds alternately on passing goats and cookies, but it prefers
+   above all things the taste of distress, especially that expressed in
+   email.
+
+   Trolls should be shunned and never fed.  Stories about them being
+   sensitive to water or light are unsubstantiated, but it may be true
+   that they can be pacified with alcohol.
+
+   The chief weapons of a Troll are its sharp tongue, its blunt
+   phrasing, and its total disregard for doing useful work.

+2.2.  The Unicorn Rampant
+
+   Many things in the IETF rely on majick.  Without pixie dust or other
+   artful contributions from the world of faerie, it is unlikely that
+   the Internet would work at all.
+
+   Software Defined Networking (SDN) is a concept whereby complex and
+   devious networks may be subjugated to the will of a sorcerer (or an
+   opensourcerer as they are sometimes know).  Fundamental to the body
+   of an SDN is the Path Computation Element (PCE) [RFC7399].  Essential
+   to the proper function of the PCE is the Unicorn that roams the dark
+   wood of the Traffic Engineering Database, rearing up and spearing
+   unwitting paths on the horn of its intellect.
+
+   Unicorns, it is claimed, can only be captured by the pure of heart
+   who have never operated a real network.

+3.  Creatures of the Deep
+
+   "Not all that crawls upon the land can rival the creatures of the
+   deep," said the great ethnographer and philanderer.  And how often it
+   has been observed that he was both wise and drunk.
+
+   The things that slide below the surface of the water remain hidden to
+   most of us, a mystery no less than the ways of the elliptic curve.
+   Most elusive of all is the Loch Ness Monster; most peculiar is the
+   Marlynne.
+
+3.1.  The Loch Ness Monster
+
+   So rare are the sightings of this beast that we must count ourselves
+   lucky to have presented here a very real etching collected at great
+   expense from a native Scott.
+
+   The Loch Ness Monster appears most often on dark nights or in heavy
+   storms when the only thing that parts the fog is the rain that lashes
+   your face.  Thus, the creature is most often visible when it can be
+   least well seen.  In this respect, it is most like clear text in an
+   RFC, which is most easy to read and comprehend when it is least
+   written.

+3.2.  The Marlynne or Sword Fishe
+
+   Getting to the point is not always something that is practised in the
+   IETF.  But there is one beast that Roams the Deeps and Never Sleeps:
+   The Marlynne, when hauled from its roost by an unsuspecting fisherman
+   for delivery to his equally unsuspecting fishwife has often been
+   mistaken for a very angry mermaid [MTFTW].  Do not mistake its sharp
+   wit for a valid argument.
+
+   As can be seen from the rendition here presented, the Marlynne is
+   happy in its work.

+4.  Spirits of the Air

+   Cloud is the latest buzz for the trendy hipster, active in
+   networking.  But be careful not to let your feet get off the crowd
+   lest your head become implanted somewhere it shouldn't be.
+
+4.1.  Ze Vompyre
+
+   Most afeared of all of the creatures is surely the vampire, for it
+   will drain the blood of any good idea until it withers or is
+   completely changed into a problem statement I-D.  More scary than the
+   dreaded Old Timer that will suck the air from a room with its hated
+   Process Discussion.  More frightening than the RFC 2119 Usage Debate
+   of Doom.
+
+   The vampire bat is sometimes mistaken for its third cousin on its
+   mother's side, the fruitbat.  That beast is equally evil and will
+   remove whole plates of fruit from refreshment tables, leaving only
+   celery sticks for latecomers.
+
+   Data that is once nibbled by a vampire may find that some of its most
+   precious bits become corrupted and drop off.  Sure protection may
+   only be achieved by placing garlic in the metadata or overhead of a
+   packet.

+4.2.  Avian Carriers
+
+   More famous than the Thrusted Pig [RFC1925] and more celebrated than
+   the Infinite Monkey [RFC2795] is the Avian Carrier [RFC1149].
+
+   This scavenger of the sky comes in a variety of bright colors,
+   perhaps an evolutionary trait enabling a hunter to distinguish the
+   carriers and drop those it considers weakest, or maybe acting as a
+   warning to predatory Buphyres so that they do not attack the carriers
+   deemed most important by the flock.

+5.  Man-Made Structures
+

+
+5.1.  Bauhaus
+
+   When Laura Ingalls Wilder was just starting out on her cover designs,
+   she agonized about what shade her little house should be.  She
+   narrowly avoided madness thanks to the timely intervention of
+   Professor Kandinsky, a prominent Moscow lawyer.
+
+   It has often been asserted that new art forms are needed to allow the
+   inclusion of colors in IETF publications.  Figure 8 clearly
+   demonstrates this to be a fallacy.

+5.2.  The Gingerbread House
+
+   Many stories have been told of how young Hans and his sister, the
+   equally young Gretha, came to be abandoned in the woods [TFTW].
+   However, it may have been Herr Grimm and his eponymous brother, Herr
+   Grimm, who first recorded the existence of a house made of
+   gingerbread (with all the trimmings).
+
+   Note that attempts to perform packet tracing using breadcrumbs will
+   usually fail owing to avian carriers who like to keep the forest
+   floor tidy (Section 4.2.

+6.  IANA Considerations
+
+   IANA might consider introducing a registry for Figure 8 to track the
+   assignment of colours to shapes.
+
+7.  Security Considerations
+
+   Stone walls do not a prison make, nor iron bars a cage: but they do
+   help.  And with this in mind, our elders encourage us always to be
+   mindful of the security and privacy of our eternal souls.
+
+7.1.  A Private Key
+
+   Keys that are shared are keys that other people have.  If someone
+   else has a key, they will use it.  If you have a key, you will
+   probably leave it in the lock or drop it in the street.  Hence we
+   conclude that keys are a security vulnerability.

+7.2.  A Security Mechanism
+
+   Locks, on the other hand, are good.  They can become rusted solid,
+   meaning that no one can open them.  What could be more secure?
+
+   And remember, a smile is the key that fits the lock to everybody's
+   heart.  So don't trust people who smile.

+   the populace has become truly debauched.
+
+9.1.  Likelihood of Misuse by the Depraved
+
+   Care must be taken lest ASCII fall into the hands of disreputable
+   characters.

+
+
+9.2.  Likelihood of Misuse by the Misguided
+
+   We should warn our children against engraving self-portraits in
+   ASCII-art and sharing them with their friends as woodcuts or in other
+   modern media.  Recall that a picture, once made, lasts forever.
+
+9.3.  Likelihood of Misuse by Corporations
+
+   The very idea that someone might patent unicorn DNA is, of course,
+   unthinkable.  Large companies only have our best interests at heart.
+
+9.4.  Oversight Facilities
+
+   Adequate oversight of all things is performed by the RFC Editor.  Who
+   has a higher moral compass or a better sense of directional values?
+
+9.5.  Other Ways of Doing Things
+
+   Radical and subversive cliques, such as that established by the
+   heretics, Georges Seurat and Paul Signac, may also be represented in
+   ASCII art.  However, doing so will, in almost every case, exceed the
+   72 character width limit used by all right-thinking people and must,
+   therefore, be avoided by all who do not wish to be doomed to spend
+   eternity in a dark corner with only dial-up access.
+
+9.6.  Concern for Wildlife
+
+   Never was a truer word spoken than when it was said that a duck may
+   be somebody's mother.  See also Section 4.2
+
+10.  References That May Be Informative to Those Who Know How To
