How can the frog's eye speak to the human brain | 1998

Köln, Trinitatiskirche

The audio-visual installation “Wie kann das Froschauge mit dem menschlichen Gehirn sprechen” (How can the frog’s eye speak to the human brain) places Jesus’s side wound at the centre of its artistic and conceptual analysis. Moving projections by overhead projectors and videobeamers are used to make the whole church into an immaterial staging in which the rules of physics seem to be no longer relevant. The tissue of media structure created specially in this way and for this place of worship circles around the themes of “religiosity”, “faith”, “fiction” and “science”. The installation addresses a connection, directed at the theme, between analogue and digital techniques for making things visible. Drops of water fall at regular intervals on to the glass surface of 9 overhead projectors. This rhythmical dripping is projected into the apse of the Trinitatiskirche by the projectors. One of two video projectors shows a computer-animated photographic sequence of an early medieval wooden figure of Jesus (from St. Georg), which was transformed into a virtually suffering Ecce Homo by an individual morphing program. The other video projection relates to the “examinability” of the mysterious events. It uses a symbolic hand that feels hesitantly down into the water and thus creates paradoxical movements in the water. The interior of the church, concentrated on pulsing sequences of movement, is also structured acoustically by a 4-channel sound production of falling water-drops, which make it possible to experience the volume of the church as a three-dimensional entity.
