I like Tarot.  I'm learning how to do readings.  It's nothing weird.  In fact, it's fairly insightful.  Tarot also has an amazing history.

A great literary reference to this is John Sanford's character Kidd.  He flips Tarot cards in the Empress File and other Kidd novels. 

My goal is to be able to do readings by the end of the year.  We'll see.  Right now, I could probably read the cards for my flatware.  That's about it.  However, if you catch up with me, and I'm carrying my deck, maybe I'll give you a reading.

You can check out the Empress File here.

The Wikipedia entry for Tarot is fairly thorough.
