This is a nice little illustration of how hard it is, and how far you can end up going, when you try to solve what seem like simple problems properly. I use OSM because i just want to know where my nearest postbox is; under the hood it's modelling plate tectonics!
Well, that’s not what the article says. Some of their image sources are using plate-locked frames of reference, and some are using global frames of reference. It’s actually inconsistent.
