The Slide Viewer:

With the use of two slide viewers, both a picture and a sound archive became available to the visitors. The archive consists of X-ray pictures of objects within the gastro-enteric area. Some of the pictures are real, others are computer-manipulated. Each picture is linked to a computer-processed sound, which is like a voice from within. The clarity of the picture-sound-connection is achieved using control engineering and software developed by my self.
