How sexy is your form?

I attended a presentation by Stephen Anderson on The Art and Science of Seductive Interactions today.  He has an approach to design that explicitly incorporates behavioral psychology and is encapsulated by a deck of cards which is generating a lot of interest in the interaction design community. 

I got a chance to talk with Stephen for a bit before and during the presentation.  He is one of the most interested (not a typo) people that I have ever met.  Anyone who can provoke me to ramble on about my workout regimen and collegiate experience must be a profoundly curious soul.  That kind of curiosity and a deck of cards will do well against any interaction design problem.

The one question left unanswered for me was whether the cards (representative of behaviors) are best utilized with specific user behaviors or whether the cards can delineate a direction for an entire application as he suggested may be possible.  I suppose I may need to attend a workshop to find out.
