If I understand this correctly, this is a paper about 3D printing physical objects, with no electronics, that send information over wifi.

ie, magic.

This is magic.


@ajroach42 The same technique can be used (probably is being used) to turn your wifi into passive radar, revealing location & activity information about everyone in the house to a snooper outside.


@seanl@social.literati.org yep. I read about that a few years back.

Also magic, but pretty scary magic.
