Yes, it's only a exe, but it isn't a big deal. I assigned certain vertices to certain face muscles/bones. The preanimated ones look better since they use weighted vertices, but you can also make some tests with realtime bone manipulation.
Basicly it's about face expressions, you could use this theory for toons as well.
To be honest, the theory is not new and it isn't my work. I used to read this in a painting arts encyclopedia by "knaurs" about 20 years ago.
