1. Just using the eulerian magnification to explore different small movements, coupled with tracking/stabilization. People also said that sound would be interesting (movements of electronics + sound captured by I forgot what that device is called)
2. Body watch? Somehow real time image but still small enough to wear.
3. I wonder if I can set up a larger scene, i.e., a silent gathering around the table with participants unmoving, and see how their blood pulses align by processing the video so that only a small frame of skin is magnified on each person. Still life-ish setting and lighting.
