In exploring the site of the artist who did the Charlie Brown painting, I found a link to a software program that was designed to help artists realize what muscle movements result in expressions. It is free to use online and if you wish to download it there is a fee. It is being used to help psychologists decode facial expressions. I thought it might help our Aspies and other autistic spectrum disordered kids learn what facial expressions mean. A sort of "magic decoder" if you will. Her is the URL: www.artnatomia.net The creator is Victoria Contreras Flores and it is called ARtnatomy. It was created in Spain in 2005.
