This project, also known as Liquid Galaxy, is based on another project known as Street View Holodeck, which is a way of perceiving the Earth from all angles, not just a birds-eye view.
Liquid Galaxy uses eight conjoined screens which fit together like a gazebo. The user can then program a sort of virtual flightpath, and then he or she can go on something that is “more like a ride than a computer program”.
In short, it really is like a Holodeck that can fly through space. It can even fly to the moon or Mars. As stated by one of the creators:
With the Liquid Galaxy, we could fly through the Grand Canyon, leap into low-Earth orbit, and come back down to perch on the Great Pyramid of Giza without even breaking a sweat.
Google has finished the latest version of Liquid Galaxy at the COP15, the United Nations Climate Change Conference in Copenhagen. It is then slated to have an appearance at the 2009 AGU Fall Meeting in San Francisco. I’m not going to be at any one of those conferences, but I do intend to go to CES in January. Perhaps Google will have Liquid Galaxy there. I would absolutely love to take the ride.
