The OpenABM website is a great resource for agent-based modelers, I often suggest to my students to visit the site to see the range of possibilities to which agent-based models can be used for.
Recently it was announced that the winner of CoMSES Net Model Recovery and Replication Drive was Torsten Hagerstrand's 1965 Spatial Innovation Diffusion Model. To quote from the announcement it is the "Earliest known calibrated and validated simulation with implicit "agent based" methodology." Sean Bergin replicated the model and provides a great ODD documentation of the model. More details can be found here.
