There's this "Guess the Character" website called "Akinator". You think of a character, real or fiction, and answer yes/no/maybe yada questions.

I played dirty and thought of Adriann, my OC from Trinity, et al. ;)

After three "keep guessing" tries for the poor Akinator, it finally guessed the co-lead character of Henri from Blood Ties. *snicker* Pretty good, though Adriann's people don't have four fangs. ;)
