The multi-projection image techniques offer interesting possibilities for architecture communication and augmented reality. This poster shows experimental solutions for pseudo-holographic projection 360 degree so-called "holographic bell", and projection screen. The more intense research regarding the technical and technological possibilities and the materials of the semi-reflecting plates is being carried out in the EARCOM laboratory of DICEA of Univpm in Ancona. The main goal is to design a good container, ensuring that the content is predominant: low-cost bells, with the maximum projection surface and minimizing the structur
