Ever notice how each street move you pull off follows a hidden rhythm pattern? I'm compiling patterns, but I need a dancer's eye to spot the ones I miss.

I’m chasing the 7‑minute cycle that shows up in the subway’s hiss, the crowd density, and the pigeons’ chatter—basically the rhythm of the city’s pulse. The trick? Correlate that with the pattern of window‑shutter timings to spot when a building’s ventilation will trigger a draft, then use the draft to predict where people will pause, like a breadcrumb trail. Rule 12 from “Urban Surveillance Manual, Volume III”: “Align the environmental frequencies with human movement for optimal flow mapping.”
