Google Earth, while perfectly usable and helpful in its own right for the common user, is something that should be experienced, and not just used. That's why Google created Liquid Galaxy, which is a set-up consisting of eight 55-inch LCD displays, which show you Earth in all of its digital glory. Google shows off the technology and system at certain trade shows that it attends. If you've ever seen it, or had a chance to use the system, then you know it's pretty fantastic. And now Google has open sourced the entire project, opening it up for everyone. But if you can't build your own, no worries -- Google will let you buy it, too.
