From The Divine Witches of Cyberspace, by Leigh Alexander:
Nathalie Lawhead, Weil’s Monkey Fortunetell collaborator, believes faith bestows certain psychological advantages, and as [people] our tendency to read meaning into nearly anything means that tools of fortune, even digital art games, can help us psychoanalyze ourselves and give ourselves appropriate care.
I've personally found tarot to be extremely useful for things like realizing what is important to me, and what I am really afraid of. Not everyone owns a deck or knows how to do readings, though, and I think there's a lot of room for different apps and other aids to help people gain insight.
(I actually know someone who's working on just such a project, but they have not taken the wraps off of it yet.)
