Presented at the 14th International Conference on Auditory Display (ICAD2008) on June 24-27, 2008 in Paris, France.With Durcheinander we present a system to help understand Agglomerative Clustering processes as they appear in various datamining tasks. Durcheinander consists of a toy dataset represented by several small objects on a tabletop surface. A computer vision systems tracks their position and computes a cluster dendrogram which is sonified every time a substantial change in this dendrogram takes place. Durcheinander may be used to answer questions concerning the behavior of clustering algorithms under various conditions. We propose its usage as a didactical and explorative platform for single- and multi-user operation
