Since barcodes are the sign of the devil (must be true, we read it on the interwebs) it's no surprise that everyone wants to replace 'em. QR codes
have been quite popular, allowing people and companies to tag their stuff with colorful decals filled with bits and bytes, and of course RFID
tags are still going strong, but a team of researchers at MIT has come up with something better: Bokode. It's effectively a tiny little retroreflective holograph that is just 3mm wide but, when a camera focused to infinity sweeps across it, the Bokodes become clear and appear much larger, captured in the video below. In this way they can contain "thousands of bits" of data and, interestingly, show positional information too, meaning the camera knows where in 3D space it is in relation to the tag. This, of course, has hundreds of potential applications ranging from grocery shopping to augmented reality
, and should lead to new and exciting ways for scholars to interpret/misinterpret Revelations.
