In Dec'09, Google wrote about Liquid Galaxy: eight 55-inch LCD screens showing Google Earth in a unified, surround view. "We've now put the features that make Liquid Galaxy into latest Google Earth, and open-source all supporting work, from Ubuntu sysadmin scripts to mechanical design of our custom frames," stated Google.
"If you think you're up to the challenge, check out Quick Start or contact End Point. Liquid Galaxies don't have to be made from eight big LCD screens; view sync features scale just fine from two to dozens of screens. And they can run more than just Google Earth."
Here's a video shows Liquid Galaxy in action:
