The Erlebnisportal (Experience Portal) in Weimar, Thuringia, Germany, is a multimedia touristic information pavilion run by the Klassik Stiftung Weimar. The space has three wall-sized screens, a surround sound system, a controlling table and the Light Cloud hanging from the ceiling. It shows films about cultural and historical places in the region of Thuringia.

The design office whitebox dresden GmbH who designed the exhibition commissioned me together with Albrecht Meixner to programme and create content for the Light Cloud. It consists of 4000+ LEDs controlled over Art-Net, they are attached on strings, connected in parallel after each other, every string a constant number of DMX addresses but with variable numbers of LEDs, hence with empty addresses on an irregular pattern. To create a list of all the LEDs, sorted by ArtNet universes and indices, appended with their space coordinates, we worked with a 3D model of the Light Cloud and multiple tables, processed half manually, half generativity.

After being able to use the Light Cloud as a three-dimensional screen, any shapes and animation, 3D as 2D could be projected on it. The Light cloud is, beside the screens, the only light source in the room. Its function is to enhance the viewing experience of the films. Therefore, in the commissioned scenes, our goal was to create a more immersive experience by recreating camera movements in the cloud, or enhancing the atmosphere of the movie, for example a sunset or foggy forest.

The following year, we shot a body interactive performance in the Erlebnisportal (see project page).
