Clebsch app for iPhone and iPad

Cubic Surfaces are a wonder of geometry. They belong to an area of mathematics called algebraic geometry. This app explores the beauty of these objects through 3D graphics and explanatory text. We consider the Clebsch cubic, which is named after the German mathematician Alfred Clebsch (1833-1872) who contributed to the field. We demonstrate the 27 lines, the Schlaefli double six, the fact that there are five planes through each line, Eckardt points, trihedral pairs and the associated Clebsch mapping and many other unique features of cubic surfaces.
