This project aims to create an affordable macroscopic physical experiment using simple principles to explore pattern formation and dynamics. Combining the Cheerios effect, a wellobserved phenomenon in fluid dynamics, with the geometric concept of aperiodic monotiles makes it possible to observe the self-assembly of complex structures from identical elements. Aperiodic monotiles are unique geometric shapes with a notable property: they can tile an infinite plane without forming a repeating pattern. The specific geometric properties of the monotiles influence the resulting formations. Perturbations can increase the complexity of clusters and make them evolve and interact with each other. This setup facilitates the self-organization of patterns on the liquid surface.
