This is beautiful! Great job!

I have a minor complaint. When I zoom in, the rate at which the globe is rotated does not seem to scale down adequately -- a few pixels, and what I was trying to zoom in on (e.g., Hawaii) zips off the screen. It feels like my mouse dragging is setting a wheel spinning, and it doesn't stop when I let go.

Thanks for the feedback - that's a good point. The sensitivity should reduce the closer you are. I'll add it to the list.

More specifically when the user clicks on a specific point on the planet and moves the mouse cursor you want that point to still be under the cursor when the mouse button is released. You can extend this construct outside the central sphere into a camera control that works across the screen and feels very intuitive at any zoom level.

Google "sgi trackball" for some interesting code to point the way.

Thank you - I'll look that up.
