The image source is arranged for projecting at least one image onto at least one concave semi-transparent reflector providing a magnified representation appearing in the distance beyond the semi-transparent reflector. The system has an adjuster for adjusting the distance between the concave semi-transparent reflector and the first image source and/or angle between the concave semi-transparent reflector and the first image source. The system enables the combination of the real world with magnified images, e.g. from video processing and computer vision techniques, offering a natural view of real scenes enriched with “real size” virtual objects. ## Claims ### Claim 1 An exhibition system for presenting a mixed reality, comprising: one of a mechanism configured to hold an image source and an image source, wherein the image
