To be clear, I don’t think it’s a scam. It may be related to what I am describing in the paper Maps of metric spaces, which has the abstract:
This is a pedagogical introduction covering maps of metric spaces, Gromov-Hausdorff distance and its “physical” meaning, and dilation structures as a convenient simplification of an exhaustive database of maps of a metric space into another. See arXiv:1103.6007 for the context.
This is pure speculation, but it looks to me that all has to do with manipulations of maps in the screen pixels space, along the lines of using scale stable and viewpoint stable zoom sequences (definitions 4.1-4.4) and (the groupoid of) transformations between these.
But how exactly? I would really much like to know!
Some time ago, after seeing the demos (check the link to the wiki page of unlimited detail), I tried to learn more about the mathematical details, but without success (which is understandable).
Don’t be fooled by the fractal looking of the territory! Probably it has more to do with the fact that in order to use Unlimited Detail, one first needs to have a territory to render, so, in my opinion, the guys generated it by using some fractal tricks.
Still looking forward to learn how exactly Unlimited detail works though.
