ASCII art: n.

The fine art of drawing diagrams using the ASCII character set (mainly |, -, /, \, and +). Also known as character graphics or ASCII graphics; see also boxology. Here is a serious example:


    o----)||(--+--|<----+   +---------o + D O
      L  )||(  |        |   |             C U
    A I  )||(  +-->|-+  |   +-\/\/-+--o -   T
    C N  )||(        |  |   |      |        P
      E  )||(  +-->|-+--)---+--|(--+-o      U
         )||(  |        |          | GND    T
    o----)||(--+--|<----+----------+     

    A power supply consisting of a full wave rectifier circuit
    feeding a capacitor input filter circuit

And here are some very silly examples:


  |\/\/\/|     ____/|              ___    |\_/|    ___
  |      |     \ o.O|   ACK!      /   \_  |` '|  _/   \
  |      |      =(_)=  THPHTH!   /      \/     \/      \
  | (o)(o)        U             /                       \
  C      _)  (__)                \/\/\/\  _____  /\/\/\/
  | ,___|    (oo)                       \/     \/
  |   /       \/-------\         U                  (__)
 /____\        ||     | \    /---V  `v'-            oo )
/      \       ||---W||  *  * |--|   || |`.         |_/\

               //-o-\\
        ____---=======---____
    ====___\   /.. ..\   /___====      Klingons rule OK!
  //        ---\__O__/---        \\
  \_\                           /_/

There is an important subgenre of ASCII art that puns on the standard character names in the fashion of a rebus.

Within humorous ASCII art, there is for some reason an entire flourishing subgenre of pictures of silly cows. Four of these are reproduced in the examples above, here are three more:


         (__)              (__)              (__)
         (\/)              ($$)              (**)
  /-------\/        /-------\/        /-------\/
 / | 666 ||        / |=====||        / |     ||
*  ||----||       *  ||----||       *  ||----||
   ~~    ~~          ~~    ~~          ~~    ~~ 
Satanic cow    This cow is a Yuppie   Cow in love

Finally, here's a magnificent example of ASCII art depicting an Edwardian train station in Dunedin, New Zealand:

                                  .-.
                                 /___\
                                 |___|

The next step beyond static tableaux in ASCII art is ASCII animation. There are not many large examples of this; perhaps the best known is the ASCII animation of the original Star Wars movie at http://www.asciimation.co.nz/.

There is a newsgroup, alt.ascii-art, devoted to this genre; however, see also warlording.
