world upside down?

[mgiraldo]

I want to remove the constraint that prevents you from rotating the globe upside down: when you rotate to the North or South poles I want it to keep going.

Here's my current experiment: https://mgiraldo.github.io/edda-globe

I tried modifying the onMouseMove function but my geometry math wouldn't help.
The specific lines of code: https://github.com/mgiraldo/edda-globe/blob/gh-pages/globe/globe.js#L321-338
