Pat Rothfuss recently worked with the folks from Albino Dragon to create a Kickstarted Name of the Wind deck of cards in which each face card features a character from the book. All those designs were discussed with Pat, and the final result is shaping up to be pretty spectacular. Are there plans, or if not - are you open to planning, - to do something like this for one or more of your own worlds?
Brandon Sanderson (paraphrased)
I know about Pat's deck, it's really awesome stuff! I can only say that I do have plans to do something similar, but you will have to wait for Words of Radiance to find out more about it.
