Absolutely awesome.  The graphics are just stunning.

This is the description of the code generating the graphics:

Of course, due to its dependence on the code revision system in use by 
the project, it tends to blow up large code additions / changes ... it 
is not artificial intelligence - the change from g77 to gfortran was 
very important to the Fortran community, but unless you know exactly at 
which time the gfortran sources were added to the GCC repository, you'll 
miss it ...

Nevertheless, recommended - I'm going to watch it for the fourth time - 
to see if I can catch up with things I missed !
