There is actually another recursive Tarot storytelling technique I know of that resembles the picture within a picture idea. What you do is draw a random card, say it is the Rider-Waite Colman Smith deck Fool (carefree cheerful man with a dog wandering near a cliff). You then look at the picture, and draw another random card for the symbol elements (eg the dog, the cliff, what the traveler has in the bundle carried on his stick etc) and so on again and again recursively for the image symbols in the new card etc. It is of course quite dependent on the art imagery of the Tarot deck you choose, but you can rapidly build a random world story from these associations. You do not have to use a Tarot deck even the wikipedia random picture could be used, but it is better with a thematic or consistent aesthetic art sequence etc
