The exhibition Rosebuds was accompanied by a publication in which all participants presented briefly one or more objects from the exhibition.
I contributed a text about the distorting mirror and the relationship of selfies, simple image editing effects and painting in the time of Mannerism. A second text compares the shape and use of slates with tablet computers.

The curved mirror that lets you see around the corner makes road traffic safer or a lot of space in the department stores' more manageable. In these enlargements, the distortions of the pictorial objects take place. Welcome to the mirror cabinet - noodle-thick or asparagus-long. The painter Parmigianino is known for nothing like his small round self-portrait from 1524, distorted by a convex mirror. You can see an enormously large hand at the front of the painting, from which the image is being painted. The refinement of the painterly technique and the tendency towards narcissism in art have been called Mannerism. Today, one can still stand in amazement in front of this small painting and take a selfie of oneself next to it. The smartphone can bend, curve, concave or convex distort the photo. The mirror cabinet for your pocket. And when I think of the digital grid with which faces can be inflated and squashed like rubber balls, I think of the perspective curieux as proof of the mastery of artistic skill with which one simply cannot impress anyone any more, and I feel a little sorry for Parmigianino.

Let's imagine ourselves in German classrooms from a hundred years ago or in those of some remote Chinese province today. The children have small devices somewhere between the standard formats DIN A4 and DIN B5, a black smooth surface, on which one notes and practices by hand and with a stylus. They are small, handy, suitable for every pocket, every satchel, black and smooth. They are written on, filled with information that can be wiped away with a flick of the wrist. They do not need an interface such as a keyboard or mouse. These little black mirrors are made of polished slate and resemble a tablet PC more than any transistor radio by Dieter Rams resembles any MP3 player. They are so similar to tablet PCs in their feel and handling that I always wonder when people talk about their child's play and intuitive use, no one notices that these digital boards, where many youngest users are no longer even aware that they are using a computer, still look like little school blackboards. And to this day, blackboards are places for note-taking, exercises or presentation. Wall boards present the big board picture, the small boards are used for the learners' notes and exercises. When the blackboards will have become white, this will not change much. The blackboard images will move from the wall to the individual devices. You don't even have to copy it yourself any more.
