Annuli is an interactive installation, which contains the book-lending statistic of the University of Applied Science Osnabrück. It visualizes the knowledge transfer of the students. The resulting growth of knowledge involves the analogy of a tree which grows when knowledge has been transferred.
The roots are the foundation of the installation. The book-lending is visualized by a coded light within the root that migrates to the tree like a nutrient. The borrowed book will then be printed with help of an integrated 3D printing head. A new data ring in the tree trunk is the result of this printing process. In a period of one semester a pie chart will be created for each day, which visualizes the amount of borrowed books from the different locations of the University of Applied Science Osnabrück.
The crown is the final element of the installation. The whole knowledge of the semester comes together in this section. If somebody submits his bachelor or master thesis, the crown will shine in coded colored lights.
