Videos filmed by attendees at heavy metal concerts [7] highlight a collective phenomenon consisting of 101−102 participants commonly referred to as a mosh pit. In mosh pits, the participants (moshers) move randomly, colliding with one another in an undirected fashion (Fig. 1(B)). Qualitatively, this phenomenon resembles the kinetics of gaseous particles, even though moshers are self-propelled agents that experience dissipative collisions.
