On a tangent: an architect claims that Portmeirion appears three times larger than it actually is, due to its complexity, being what he calls a "fractal town":
"Distances will therefore seem smaller in places where people look at their feet and there is lots of traffic. We can use this to make space from nothing. It would seem that vastly more information is absorbed during a walk in Portmeirion than it is in Manchester."
He said previous studies in the US had indicated that our vision expects the world to be fractal. "This may explain why non-fractal environments such as car parks feel oppressive," he said.
