As visual artist Anna Heydel works with photography, projections, objects, sculptures, and installations. VISIONICUM (since 2016) is a project, in which she brings together all these practices. The name describes the development of a visual language that initially emerged from the combination of Braille—the writing system for the blind—and visual elements, but has since completely developed away from it and created its own, wilder formal language.

The works from the first three creative phases (2016–2023) are based on words with various meanings in Braille (e.g., synonyms for the word to see), which permeate, transform, and alienate reality in different ways. In this way, the visual perception process—which consists of seeing and not seeing—becomes a creative element that enables concrete intervention in the space.

The more recent works (since 2024) are no longer based on the structure of Braille. The driving force becomes the freely moving dot, a multitude of dots that embody the view and the imagination. These circular forms are constantly changing shape and are often not even recognizable as such, depending on the technique used to create them. The possibilities are constantly evolving, Anna Heydel works with both photographic and non-photographic media, digitally and analog, using projections and a hole punch on small objects all the way up to large installations.

Various levels of intervention perforate and transform familiar and unfamiliar dimensions in the works. With the help of a quasi-magical eye or an undefined greater power, Anna Heydel is able to alter the existing structure of the present. From a world in which the possible fails, a world emerges in which the impossible becomes realizable.
