Liquid Galaxy projecthttps://www.liquidgalaxy.eu/
Liquid Galaxy is a remarkable panoramic system that is tremendously compelling. It started off as a Google 20% project to run Google Earth across a cluster of PC's and it has grown from there!
Liquid Galaxy hardware consists of 3 or more computers driving multiple displays, usually one computer for each display. Liquid Galaxy applications have been developed using a master/slave architecture. The view orientation of each slave display is configured in reference to the view of the master display. Navigation on the system is done from the master instance and the location on the master is broadcast to the slaves over UDP. The slave instances, knowing their own locations in reference to the master, then change their views accordingly.
The Liquid Galaxy Project, while making use of Google Earth software, does not develop the Google Earth code-base itself. Google Earth is not open source software, although it is free (as in beer). Instead, the Liquid Galaxy Project works on extending the Liquid Galaxy system with open source software both improving its administration and enabling open source applications, so that content of various types can be displayed in the immersive panoramic environment.
