Just got a Project Tango Development Kit tablet and have worked through some of the demos and examples.
Some older blog posts use the log files from a "Tango Map

It appears that more than a few of the contributors to the Tango project were hired or bought by google. As an example most of the links to code and/or articles by Hidof are MIA, only a facebook page with few clues remains. The internet archive's wayback machine has a few snapshots of their website for the curious.
