Simulates how hundreds of listeners react to a DJ set in real time: every persona lives in Qdrant as a 532-dimension hybrid vector, scored every 15 seconds with drifting preferences, while the crowd's convergence or polarization is projected onto a 2D map.
Most entries at a vector search event treat the store as an index; this one uses it as the substrate for a simulation, a genuinely different reading of the same tool. Quoting concrete design values - the dimensionality of each persona vector, how often preferences are rescored - signals it went past the idea stage. The output format may matter most: projecting whether a crowd converges or splits onto a 2D map makes collective behaviour graspable in seconds.
Eight winners across two Qdrant hackathons all treat the question of what to remember, and how, as the actual subject.
When something that is not a business problem wins, there is always a mechanism that lands instantly.
