It's not a very detailed explanation but the write-up is here: http://techn.ology.net/visualize-move-protection-and-threat-...

It's written as a server program in Perl, but it's relatively easy to install and run on your own computer:

> git clone https://github.com/ology/Chess-Inspector.git

> cd Chess-Inspector

> perl Makefile.PL

> make

> sudo make install

> perl bin/app.pl

Then open http://localhost:3000 in your web browser. Voila!

These instructions are incorrect. Please check out the repo README. (Basically relace all the "make stuff" with `sudo cpan .`)
