> reconstruct a conversation by analyzing the movement of the glass on a window to the room where people are talking

May I please have a link to more information? I wasn't able to find anything, and this is very interesting.

"reconstruct conversation glass vibration" brings up a lot of relevant results from a 2014 story from MIT. Sounds like it works in principle with any medium that can have its visible vibrations monitored (bag of chips is the main example, but they talk about other options such as plants or a glass of water).

Yes I think that's what I was referring to; I may have confused glass and chips but it seems it works with either medium.
