Frank, thanks for your input, a working example would be great! iiuy, Singularities aren't an issue in the example given as the brick wall has a fixed length. ie zooming could present a reasonable facsimile.

This would allow for perspective distortions. But I'm not sure if this wouldn't be too difficult for implementors since singularities (the horizon) would need to be dealt with, in case they become visible. There was a question before regarding perspective distortion of text. And I remember someone suggested using the filter primitive feDisplacementMap. But no solution for creating the correct image data to use for in2 was found then. Maybe this was resolved in the mean time. I haven't seen something like it done in SVG yet. But that would be cool. So I hope someone will come up with a working example.
