Sorry, this panorama uses the original "qtvr" style navigation. Google streetview, maps, and Earth use "click and drag" navigation. There is currently a religious war going on in the pano community about which one is better. I tend to agree that the "click and drag" has become the standard.
I guess I don't get what's so horrible about giving people a choice. This is just a Quake-style mlook implementation at the end of the day, and gamers are used to being able to select the mlook polarity.
But no, there has to be a jihad, and somebody has to "win."
