Any interesting urls dealing with mirroring, technique wise.
(Moves to immitate / moves not to immitates / different moves different results...moves for girls / moves for buisness relations / friends)

+ the fruition stage is very often found in couples ( also long term friends) . Man + women who stayed together for along time + passionatly love each other , tend to do lots of things simultaniously (saying the same thing / reaching for the same object and so on )

This is the highest level of mirroring , that you cannot reach artificially , so I belive ! + This comes naturally with time...
