The Poznań Fotoplastikon dating to the beginning of the 20th century is a stereoscopic theatre based on the Kaiserpanorama system of rotating stereoscopic images. It is where the 3D photographs taken by the astronauts during their trip to the Moon can be seen. The photographs were taken using the specially designed cameras - the astronauts were taught to take so-called sequential stereoscopic photographs which gave an illusion of a three-dimensional image. The photographs come from the album co-authored by David J. Eicher and Brian May (the band Queen's guitarist).
