We discuss on the potential of suspensions of gold nanoparticles with variable refractive index fol' the possible physical realization of in- relief virtual dynamic display of plane images. A reasoning approach for a vision system to display in real- time volumetric moving images is proposed based on well- known properties of optical media, namely the anomalous dispersion of light on certain transparent media and the virtual image formed by a refracting transparent surface. The system relies on creating mechanisms to modify the refractive index of in- reliefvirtual dynamical display (iVDD) bulbs that ideally would contain a suspension of gold nanoparticles each and that might be ordered in an array filling up a whole screen.
