I have a complicated and interconnected module library. In my t/ directory, I have 0.t script which runs all the other *.t scripts. It then runs figlet to tell me:

 ___ _  _  __  __  ___  ___ ___
(_-<| || |/ _|/ _|/ -_)(_-<(_-<
/__/ \_,_|\__|\__|\___|/__//__/

or

  __        _  _
 / _| __ _ (_)| | _  _  _ _  ___
|  _|/ _` || || || || || '_|/ -_)
|_|  \__,_||_||_| \_,_||_|  \___|
[download]

Works nicely, since I can run individual test groups as I develop them, then a sanity check of several hundred tests before I commit to version control.
