In this paper we present Durcheinander, an interactive system designed to support learners in understanding agglomerative clustering (AG) processes. This datamining approach is mainly used to unveil structural relations in high-dimensional datasets. Durcheinander operates on a two-dimensional dataset comprising of the positions of 20 or more objects located on a tabletop surface. Changing the objects' location causes the system to compute an updated dendrogram that represents the actual dataset. If the dendrogram's configuration differs substantially from its predecessor, a spatial sound event that represents the internal structure is rendered in realtime and played back to the users by a multi-channel audio system surrounding the table. Replaying that configuration is possible by knocking onto the surface.
