This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.

This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?

Just post some stuff and don't spam.

This is at JFK, does anyone know what they are used for? There wasn’t an obvious time when it was taking a picture.

Looks a lot like my 3d scanner / Like an Xbox Kinect / Apple Face ID. On a ticket machine That’s just creepy.

yep, structured images are projected, then left right cameras capture images, the device compares the differences in each image and can use that to build a rough 3d model of the face. I strongly suspect these are used to make sure people aren't using printed images to spoof the verification - but never put it past the state to horde data and hoover up everything they can.
