Keys: WASD, space, r
An improved JavaScript implementation of the simulations presented by Matt Bierbaum This simulation includes social rules to make more realistic moshing behaviour Based on the paper Collective Motion of Moshers at Heavy Metal Concerts. More details are available at Itai Cohen's group website including videos of mosh pits, full simulations, and a brief description.
Play around. The buttoms above set up interesting initial conditions while the sliders allow you to control the parameters of the model. The keys WASD allow you to apply external forces to active MASHers. The graphs, as listed from the left, are a time average of the angular momentum, the current angular momentum, and the speed distribution. Read the help for more information. HTML to embed.
