The impact of small drops on a water-covered sand bed provides a simple physical system to study erosion, sand entrainement and pattern formation. The patterns evidenced here start out nicely circular but this circular symmetry gets lost once the dropping frequency increases above threshold. Three-dimensional structures then form and grow logarithmically in time.
