The Swiss geologist and mineralogist Louis-Albert Necker belonged to a family rich in scientific celebrities. Though a professor at the Académie de Genève for 25 years and author of numerous publications, he is mainly remembered today for his description of the “Necker cube” optical illusion and for leaving Geneva to spend the last 20 years of his life in Portree on the Isle of Skye. As a first step towards assessing Necker's contribution to science, a full list of his publications is presented, with comments about their citation in previous bibliographies and about published translations and abridgements. Information about the surviving specimens from his scientific collections, most of which are in the Muséum d'histoire naturelle de Genève, is also presented.

AbstractThe machine theatre in France achieves its peak in the second half of the seventeenth century. It is the construction of machines that permits the adequate representation of the third dimension on stage. This optical illusion is created by flying characters, as heroes, gods, or demons moving horizontally and vertically. The enumeration indicates that only characters possessing either ethically exemplary character traits or incorporating sin are allowed to fly. Therefore, the third dimension indicates bienséance – or its opposite. According to this, the following thesis is deduced: The machine theatre illustrates via aesthetic concerns characterising its third dimension an ethic foundation. Ethic and aesthetics determine each other in the context of both, decorum and in theatre practice. In order to prove this thesis three steps are taken. First of all, the machine theatre’s relationship to imitation and creation is explored. Second, the stage design, representing the aesthetic benefits of the machines in service of the third dimension, are explained. Finally, the concrete example of Pierre Corneille’s Andromède is analysed by pointing out the role of Pegasus and Perseus.

Art of animation as an analysis of movement is based on the theory that the vision remains on the eye after the disappearance of the actual image, and this scientific theory is the same that the film industry was built upon. Recently, various techniques and ideas have entered the print design process as a means of expressing a phenomenon subject to the human will to change and elevate our aesthetic awareness and feelings, which rise in various forms of designs that reveal themselves in design work and are embodied in animation films. The design artwork falls within a group of intertwined elements fused with each other, reflecting the peculiarity of this work, as it is innovation and creating new and interesting things, so that the design is suitable for the desired purpose and beautifully. Perhaps the simplest type of optical illusion that can clarify to us the idea of the impression of the existence of an image that does not actually exist is represented in the decree paper. Key words: Design thinking, Typography, Animation films
