Deluge in Norway

300,000 Norwegians move house every year. If the pattern made by this process could be compressed into one short animation, what would would it look like? What could you learn about your country from such an animation, if anything?

Deluge is a C++ application designed to answer these questions. The underlying data was generated by cross referencing Norwegian tax records from 2006 and 2007 to find changes in postal codes.
