I couldn't help but notice that it doesn't let you zoom in on the "dollhouse" view, i.e. the one actually showing the 3D model. No way to see how these models look up close.

This'll work great for navigating buildings—I can imagine it being a hit with real-estate sites—but the hiding of detail in the 3D view suggests the tech wouldn't work as well for other applications, like VR. (I'd love to be wrong here, though!)
