Abstract
A set of simple identities is utilized to build up new projective twistor diagrams for massless free fields of arbitrary spin in real Minkowski space. It is effectively shown that the inner structure of the configurations which arise out of implementing the relevant techniques has characteristics that are different from those of the conventional diagrams associated with the Kirchoff-D'Adhemar-Penrose integral expressions. A nonhomogeneous version of the configurations is also provided.
