In a similar vein, Taylor Otwell from Laravel writes his comment blocks exactly three lines long and each line is three characters shorter than the line above, e.g.
/*
|--------------------------------------------------------------------------
| Application Name
|--------------------------------------------------------------------------
|
| This value is the name of your application, which will be used when the
| framework needs to place the application's name in a notification or
| other UI elements where an application name needs to be displayed.
