Like Microsoft’s demo site ‘Explore a more beautiful web’ for their newest browser IE 9, Mozilla has also started a demo site for showing what their next browser Firefox 4 can do with modern web technologies like CSS3, HTML5, WebGL, etc. The latest example is an awesome online planetarium where you can learn a variety of interesting facts about our Solar System.
Built with HTML5 and CSS3, this planetarium shows the mind-boggling possibilities of these modern web technologies. This planetarium makes use of CSS3 Transitions and Transformations for animation, so no flash plug-in is required.
Most of these web technologies are already included in Firefox 4 RC. Download Firefox 4 Release Candidate now and explore our Solar System!
