Even when you're sitting still, your whole body is moving. And with new technology from MIT, that motion is getting blown up into creepy, visible footage of everything from the wiggling of your eyeballs inside your skull to the rippling of a pregnant woman's stomach as a baby moves inside.
You can even use these algorithms to listen in on someone's conversation by keeping an eye on the objects around them. MIT researchers recently published a study in which they extracted intelligible audio by analyzing the movements of a nearby bag of chips. By magnifying its movements, they were able to reconstruct the soundwaves that were causing it to flutter imperceptibly.
A lot of the coolest examples of this video magnification come from people outside the research team. Lead researcher Michael Rubinstein has made the software totally public, so you can create magnified videos of your own -- and do with them what you will.
