Show HN: Today's cities on a globe of Earth's tectonic past and future

This is really cool!

I'm wondering what data you're using and if you can impose a more precise coordinate system into the visualizations with ways to track a specific point (perhaps starting from polygons or GPS coordinates). It seems the visualization includes sea level rise but it's hard to figure out if its getting other details right like the California’s Transverse Ranges uplift (~20 mYa to present) which moved the Los Angeles basin several hundred kilometers northwest all while San Diego and Baja California were also rearranged.

Is the triangle ‘play’ button supposed to do something? Maybe hug of death going on?
