It was around 1970 that Verner Panton designed wall and ceiling elements in the shape of semi-circular spheres. A mass product for a manufacturer in Basel, these pieces came in a number of different colors. Not long before this, Panton had developed similar modular wall and ceiling plastic cladding for the now legendary “Visiona II” exhibition, which was subsequently displayed at the 1970 Cologne furniture fair. This special show, which was entirely Panton’s brainchild and was presented on a temporarily converted excursion boat on the banks of the Rhine, was commissioned by the pharmaceuticals company Bayer. The intention behind “Visiona II” was to draw attention to the various possible applications using plastic in the context of living and furnishing via means of a “visionary” and spectacular spatial presentation. In the mid-20th century, modular systems were of significant importance in the field of architecture and design, both for façades and for interior decoration. Around this time, not only Panton but also numerous other designers and architects had begun to develop systems of this kind. Specialists such as Helmut Rhode, who designed a façade module for the Horten department store group, and Claude Ferret, who used aluminum panels to clad the Ecole Nationale Superieure d'Architecture et de Paysage de Bordeaux are two such examples.
