rtoz writes Researchers at MIT, Microsoft, and Adobe have developed an algorithm that can reconstruct an audio signal by analyzing minute vibrations of objects depicted in video. In one set of experiments, they were able to recover intelligible speech from the vibrations of a potato-chip bag (video) photographed from 15 feet away through soundproof glass.

      Are they not doing this already in CSI?

Isn't science wonderful?

    Clearly, if your work is that important having a window office becomes a sign of extremely low status and institutional nonimportance, rather than professional advancement...
