Last December, we wrote about our immersive Google Earth environment, Liquid Galaxy: eight 55-inch LCD screens showing Google Earth in a unified, surround view. Since then, we?ve taken it to a lot of conferences, built Liquid Galaxies in Google offices all over the world and even put one in the Tech Museum in San Jose, Calif. We love watching people try it for the first time. Almost everybody wants to see their own house first; but then they start to explore, and we can never guess where they?ll choose to go next.
