                \XXXXXXXXXXXXXXXXXXXXXXXXXX/
                  ""VXXXXXXXXXXXXXXXXXXV""
Dragons, elephants, koalas and lot others.
The cowsay command supports quite a few options to modify the behaviour of the cows. Check the man page.

2. xcowsay

$ sudo apt-get install xcowsay

xcowsay is same as the cowsay

3. sl - Steam Locomotive

$ sudo apt-get install sl

With the sl command, a steam locomotive will run across your terminal from right to left. And it looks like this
(@@) (  ) (@)  ( )  @@    ()    @     O     @
                     (   )
                 (@@@@)
              (    )

            (@@@)
         ====        ________                ___________
     _D _|  |_______/        \__I_I_____===__|_________|
      |(_)---  |   H\________/ |   |        =|___ ___|      ________________
      /     |  |   H  |  |     |   |         ||_| |_||     _|
     |      |  |   H  |__--------------------| [___] |   =|
     | ________|___H__/__|_____/[][]~\_______|       |   -|
     |/ |   |-----------I_____I [][] []  D   |=======|____|_________________
   __/ =| o |=-O=====O=====O=====O \ ____Y___________|__|___________________
    |/-=|___|=    ||    ||    ||    |_____/~\___/          |_D__D__D_|  |_D_
     \_/      \__/  \__/  \__/  \__/      \_/               \_/   \_/    \_/
The sl command has 2-3 additional options, that can be found in the man pages.

4. figlet - draw banners

The figlet command can be used to draw large sized text banners. I remember seeing such banners as the welcome message of socket daemons/services, when connecting via telnet.

$ figlet Welcome
__        __   _                          
\ \      / /__| | ___ ___  _ __ ___   ___ 
 \ \ /\ / / _ \ |/ __/ _ \| '_ ` _ \ / _ \
  \ V  V /  __/ | (_| (_) | | | | | |  __/
   \_/\_/ \___|_|\___\___/|_| |_| |_|\___|


5. toilet - draw banners again

The toilet command is similar to the figlet command, that it draws large sized text banners using smaller characters.
$ toilet Welcome
                                                 
m     m        ""#                               
#  #  #  mmm     #     mmm    mmm   mmmmm   mmm  
" #"# # #"  #    #    #"  "  #" "#  # # #  #"  # 
 ## ##" #""""    #    #      #   #  # # #  #"""" 
 #   #  "#mm"    "mm  "#mm"  "#m#"  # # #  "#mm"
The toilet commands supports a wide range of options like unicode support, colored fonts, filters etc. Check out the man page. To draw the text in a bit different way, try the following command

 $ toilet -f mono12 -F metal Linux


6. cmatrix - The MATRIX

$ sudo apt-get install cmatrix

The command cmatrix draws the Neo style matrix on your terminal and makes you feel a little more geekier.
