This quick TED talk entry is courtesy of TED.com. Meet the â€œmotion microscope,â€ a video-processing tool that plays up tiny changes in motion and color impossible to see with the naked eye. Video researcher Michael Rubinstein plays us clip after jaw-dropping clip showing how this tech can track an individualâ€™s pulse and heartbeat simply from a piece of footage. Watch him recreate a conversation by amplifying the movements from sound waves bouncing off a bag of chips. The wow-inspiring and sinister applications of this tech you have to see to believe.
