That one is super cool...

I found a site http://charahub.com/. There are two personality types they ask about. The Jung type which is the 16 characters and Enneagram http://www.eclecticenergies.com/enneagram/test.php. They also allow you to build characters and link them within a group.

I just found it this year and am building my characters for NaNo here to try it out.
