Cluster deposition on flat substrates can lead to surprising patterns. This pattern formation can be related either to phenomena taking place at the substrate surface or to dynamics in the cluster beam. We describe the observation of a pattern of particles each being an aggregate of Cu clusters. Such patterns obey scaling with respect to particle size, the typical scaling exponent being 1.18. The origin of the observed scaling is discussed.
