For this series of experiments a very large number of scenes  are  available
and there are too many to have them all permanently installed for  VGHD.  In
order to reduce  things to a managable level only a relatively small  subset
of the available scenes are delivered in the main folder where they  can  be
seen by the VGHD program and the others are kept in a series of  zip  files.
These files have the extension .zip and also their names begin  with  z-  so
that they all are sorted together by the file manager.
 
Each zip file contains the the scenes for one of the main subsets of  scenes
and the names of the zip files reflect their contents.  There  are two extra
zip files, z-000 Defaults.zip,  which contains copies of the default set  of
scenes that are delivered in the main scene folder, and z-000 Misc Stuff.zip

Several of the experimental series,   such as the basic static A an B series,
are only delivered in the zip files as the default set of scenes  only  has
those that I find most interesting.  In  other  cases  the zip files contain 
some extra scenes because the default set covers the main points  that   the
particular set of scenes is intended to investigate.

Of particular importance is that the main set of scenes generaly  only  have
those scenes that start from function number 1.  This  is all that is needed
if you have configured VGHD to continue with a single scene for a half  hour
or so, but is not adequate if it is configured to change scenes after a  few
minutes. If you do not want to change the VGHD setting then access to  those
scenes that cover the higher  numbered  functions  requires  installing  the
corresponding scene files, e.g. the C21, C41, C61 and C81 scenes  to  extend
the coverage provided by the C01 scenes.

A set of scenes, or individual scenes, in the zip files can installed  where
the VGHD program can find them simply by copying them into the  main  folder
for this set of scenes. 

It is recommended that the majority of the scene files are kept in  the  zip
files and only copied to the main scene folder when you want to look at  the
particular scenes they represent,  and  that   once they have been looked at
only those that you particularly want to keep are left in the   main  folder.
As one of the zip files contains the default set of scenes  it  is  safe  to
delete any,  or all,  of  the .scn files from the main folder at any time as
they can always be restored from the zip files.
