Case study - 3D Globe in HTML5

HTML5 brought some exciting new tools for web developers. To me, the most appealing ones are the canvas tag, and the geolocation API. With canvas, you can create graphics rendered right in the browser, just like with SVG, but in a standard HTML environment.I have played around with this new tag and created a demo to display geographical coordinates on a 3D sphere.
