The main pre-requisite seems to be the ability to sketch (i.e. quickly draw) the ideas that you're hearing in a real-time flow. I can do the latter (i.e. synthesize and absorb the talk with bright visuals in my imagination), but putting them down on paper is the daunting task.
Is this the type of art that's only within the grasp of gifted artists? I'd be happy even if I could quickly and accurately sketch rage comics or simpler xkcd stick figures, but alas even those require an inordinate amount of time.
