Google has added Labs to Google Maps; Google has used the Labs category to offer some quirky, optional and experimental features to its established products (when Beta isn’t enough, I guess). In the case of Google Maps, that means some interface features like drag-to-zoom, tools that allow you to see a location’s latitude and longitude, bird’s-eye oblique imagery that was previously available only through the API, and rotatable maps (to create, I suppose, your own upside-down map of the world). Plus a bunch of other stuff. See James Fee and All Points Blog.
