This paper presents a decentralized control policy for symmetric formations in multiagent systems. It is shown that $n$ agents, each one pursuing its leading neighbor along the line of sight rotated by a common offset angle $α$, eventually converge to a single point, a circle or a logarithmic spiral pattern, depending on the value of $α$. In the final part of the paper, we present a strategy to make the agents totally anonymous, and we discuss a potential application to coverage path planning.
