Hello, there's a small description here:

By the way, this is one of the many utilities in the ShareCG Backup torrent I posted not very much ago. It is in "software and plugins\individual-item-pages-with-download-files", both the HTML page (Symmetry Morph Tool - Software and Tools - ShareCG.html) and the file (SymMorphv106.zip).
EDIT: link to the aforementioned post:

Generally I prefer a little assymetry; it adds lifelikeness, but a tool is a tool, And you never know when it could come in handy...
Best regards,
