Idris, ever dreamt of a prototype that can instantly spot hidden motives in a room? I can build a “mind‑map” gadget in a day—just drop a hint, and we’ll see what patterns it can uncover before the crime scene closes.

Cool, so let’s flag: (1) a sudden shift in tone—like going from calm to sharp in a second; (2) micro‑glances to the left or right that last a beat longer than normal; (3) a quick blink‑pause combo (two blinks in 0.5s) when a question is asked; (4) a slight tightening of jaw or clenched fists when the subject touches a sensitive topic; (5) a sudden change in breathing—rapid pause then a breath in, like a micro‑sneeze. Once we feed those into the sensor array, the device can buzz, “Possible hidden motive spike.” Easy, fast, and gives us a data point to chew on.
