Since its first meeting devoted to this topic in 1994, discrete tomography has developed into a powerful imaging tool with a remarkably rich theory connecting various mathematical and application fields. Unlike its "continuous" counterpart, computerized tomography (CT) introduced in the 1970s, discrete tomography deals with the reconstruction of discrete objects, which are typically accessible through data that has been acquired from a small number of angles. In this rather general talk, I would like to illustrate several recent developments in this field focusing on problems of revealing structures in numbers, metals, and plasma columns. Among the persons and entities that make an appearance in this talk are the Beatles, the U.S. Census Bureau, Leonhard Euler, and Bavarian farmers.
