Sorry that this is somewhat tangential to orienteering, although it does relate to maps, reality and travel, and since there are strangemaps fans and cartographers here...
A while ago I saw a cartogram of the USA that displayed 'distance' as a function of air travel time rather than miles. As you might imagine, it squashed the northeast US bunched up bits of California with it and ballooned out the midwest and Idaho. I want to use it in a talk I'm giving tomorrow (about dialect distances vs geogrphical amongst other things) but I can't find it anywhere. I thought I saw it on
strangemaps.wordpress.com but looking through the archives didn't find it.
A further question: anyone know a (preferably free) program that'll do this sort of multidimensional cartographic scaling?
