Post about creepy /x/ technologies.
I'll list a few to start.
>Machine Identification Code
Every piece of paper you print on a printer has a secret invisible code that reveals information about your specific printer. It can be used to reverse trace where a paper was printed from.

>Mind Control Devices
Doctor Jose Delgado as well as several other doctors around his time realized that the brain actually makes decisions before the human is aware of it, basically proving there's no free will and the brain can be controlled with a computer implant. Delgado and other doctors were able to remotely control human beings like raising their arms involuntarily or stopping them from walking, or even triggering an angry violent behavior artificially in otherwise calm people.

>XFinity WiFi Motion
XFinity can use WiFi to accurately detect motion in your home without the need for cameras or conventional motion sensors. According to some customers it is accurate enough to notice the waving of a hand.

Finally is one that has no name but we all know it is real. Advertisers have some kinda network where they pass around our information in real time, you might be talking to your wife about how you like hot cocao and then 5 seconds later you get an ad about hot cocao.
Lol.
