I found a simple but powerful tool for linux which allows you to create ASCII art logos for your command line applications.
Its name is figlet, and can be downloaded from your package tool (apt-get, yum, …), at least in almost all the Linux distributions.
To create a new logo you need to invoke (from your shell):
# figlet <TEXT>
# figlet abiquo
You can also specify the alignment of the text, and the font you want to use:
#figlet -c -f script abiquo
-c : Centered
-f : Font
Sample results:
