Digital Trends: Prototype Device Lets You Easily Switch Between Privacy Options Online. “Even people who consider themselves to be in the know about tech can get flummoxed when it comes to the subject of online privacy. Who is tracking you and how is something many users don’t follow, and there are few simple means of learning this information. That’s something a nifty piece of hardware created by Spanish designers Roman Torre and Angeles Angulo hopes to address. What they’ve developed is a 3D-printed prototype of a desktop device, called Thero, that allows users to switch between encrypted communication methods simply by turning a dial.” How cool is that?
