Very well done. The animation of plate movements give me a real sense of vertigo! Earth is old. o__O

For me at least, it would feel more intuitive to have the distant past on the left and the current date on the right. I'd also love an option to keep the current location centered while manually dragging the slider.

EDIT: Also, could optionally overlay lat/lon lines to help anchor the globe as it rotates? It's hard to understand the plate movements relative to the Earth.
