_zur form (_on form) is a collaborative mixed-reality installation by Florian Grond, Thomas Kienzl and Gabriele Engelhardt. In it, mathematical formulas are transformed into 3D forms and are presented as sculptures together with a tangible mixed reality installation. The project also features photographs of the support forms, the negative casts that emerge out of the form production process.

_zur form makes a contemporary contribution to the well-established tradition of representing mathematical functions as 3D forms, which dates back to 19th-century Germany. The early forms inspired a number of artists in the 19th and 20th centuries, and also became the point of departure for the conception of our project.

In German, the word "begreifen" (to understand) literally means to grasp an idea, as with a hand. The transformation of formulas into forms also emphasizes the original meaning of the word "information," which is "bringing into form." Thus, by making tangible objects out of abstract mathematical concepts, the sculptures and their representations underline both the material and physiological aspects that pertain to the construction and accessibility of knowledge.

The represented forms emerged out of Florian Grond’s research into the stability of chaotic attractors, which are solutions to nonlinear differential equations. Grond developed algorithms that accentuate the curious topological properties of chaotic attractors.

Thomas Kienzl developed a tangible mixed reality interface (MRI) for the project. The MRI allows for a tactile manipulation of the mathematical objects in virtual space. Gabriele Engelhardt’s photographic work focuses on various sculptural elements. With her photographs of the negative casts of these forms, Engelhardt extends the tradition of using mathematical functions as model objects in the history of photography.


Thomas Kienzl


He studied Architecture in Graz. In 1994 he founded Kommerz, a company specialized in developing interfaces in the fields of interaction design and visual media.

Gabriele Engelhard


She studied Education for children with special needs and History. Later she turned to sculpture, media art and photography. One recurring theme in her photographic work is the modeling of landscape as sculpture.

Florian Grond


Florian est né à Graz (Autriche) en 1975.

Florian a étudié la chimie à l’Université Karl Franzens de Graz, à l’Université de Montfort à Leicester et à l’Université Eberhard Karls de Tübingen.

Depuis 2002, il travaille au ZKM (Centre pour l’art et les médias) à Karlsruhe, en Allemagne.

Son centre d’intérêt scientifique principal concerne les "systèmes dynamiques non linéaires" et la "sonorisation scientifique".

Depuis 2002, il a publié de nombreux articles pour des revues scientifiques et journaux, et depuis 2004, il participe à des expositions d’arts numériques en Allemagne (Karlsruhe), Autriche (Graz), Suisse (Aarau), Danemark (Esbjerg), Italie (Gènes) and Japon (Hakodate et Tokyo).
