The official Google Earth plugin is one free download that makes all sorts of cool stuff possible in your browser. There's a full screen version of the program (complete with underwater views and 3D buildings) which can be searched by entering queries at the end of the URL. There's a framed version with support for layers, historical imagery, day/night cycles, and the Google Sky starmap. Less useful but more fun are Google's collection of "experiments" demonstrating the possibilities of the Earth API, including a "Geo Whiz" geography quiz, an antipode locater, a 3D first-person view of San Francisco, a virtual route-follower, and MONSTER MILKTRUCK!, a crazy fun driving simulator that lets you careen a virtual milk truck through the Googleplex campus, ricochet off the Himalayas, or explore any other place you care to name. Lots more can be found in the Google Earth Gallery -- highlights include a look at mountaintop removal mining, a real-time flight tracker, a guide to trails and outdoor recreation, a 360 panorama catalog, geotagged Panoramio photos, and the comprehensive crowdsourced Google Earth Community Layer. And while it's too large to view online, don't miss loading the Metafilter user location map into a desktop version of Google Earth! [more inside]

Despite plate tectonics' popular acceptance in the 60s, Samuel Warren Carey, the father of modern expansion tectonics, was publicly promoting his theories of an expanded earth as late as 1981. One of the theory's most prominent modern spokesmen is comics artist Neal Adams, who has created a number of informative videos about a new model of the universe that even manages to explain why the dinosaurs died out.

What would happen if the earth stopped spinning? ArcGIS was used to perform complex raster analysis and volumetric computations and generate maps that visualize these results.
