Fascinating! A few questions:

- once the LED has slowed down to 60 bpm, do you keep it at that tempo for the rest of the day? for a few hours? do you ever go back to 120 bpm and then go back down?

- generally speaking, how did you come up with the idea?

- do you think that a software version (i.e. some blinking pixels in the top right corner of a monitor) would work, or is the intensity of the LED (i.e. the fact that it's not part of the monitor) part of the reason why it works?

- could you also talk about the heart-rate sensor - how do you use it / how does it affect the bpm algorithm?

Thanks!
