I think it would be amazing indeed to view a reconstruction of the usual kinds of mirrored and refractive spheres that behaved as if it were really there! I've been reading a couple of articles: _Binary Fraunhofer Holograms, Generated by Computer_ A. W. Lohmann and D. P. Paris Applied Optics Vol 6, No 10 p. 1739 and: _Minimization of Reconstruction Errors with Computer Generated Binary Holograms_ R. A. Gabel and B. Liu Applied Optics Vol 9, No 5 p. 1180 I'm inspired by the cover of Stewart Brand's new book, _The Media Lab_ Any information which might help me understand this technology is welcome.
