Well, Australia's moved about a bit these last few hundred million years, but I don't think it's ever been anywhere near North America! http://www.kartografie.nl/gondwana/gondwana_gif.html. (For a view including North America which spreads the globe out, see www.odsn.de/odsn/services/paleomap/animation.html, and for one which abstracts from the globe entirely, letting the drift of tectonic plates resemble a lava-lamp, see http://piru.alexandria.ucsb.edu/collections/animations/Pangea.mov. Is it a coincidence that the last one is American?)
In any case, it's clear I'm heading to a whole new neighborhood!
