Ever since the Internet was introduced in the 1990s, every subsequent decade has seen massive leaps in digital technology and design sensibilities. Obviously, all kinds of media and digital products that exist beyond the scope of the Internet have been either introduced or heavily refined and advanced since the turn of the millennium. Far more computing power has become widely available to allow a given product to both carry out its familiar functionality on a much grander scale and support entirely new functions that would have required a lot of specialized hardware in just the previous decade. Because of the different kinds of products that now make their way into the hands of consumers at affordable prices, this expansion of the types of functions that a given product can support often takes the form of new ways for separate products to mutually interact.
For example, throughout the 2010s, streaming services had effectively amounted to websites that allow users with webcams connected to their systems to broadcast themselves "on air" in a similar manner as live talk shows on television and the like. As the years have gone by, the cameras themselves have widely adopted features that would have previously been seen as prohibitively expensive "novelty" functions, such as the ability to scan and register the movements of the user's own physical face. The technology of webcams has improved to the point that it is not an uncommon feature for one to detect each blink the user makes with their eyes.
Since websites have become much more sophisticated in their own right and can interact in new ways with data sent by external devices such as webcams, it is now possible to create a website that changes its displayed elements whenever the user blinks in the real world. An example of this recent innovation is located at realless.glitch.me. This, of course, is an experimental effect that can only happen if the user knowingly consents to training their webcam on themselves for the purposes of a website they presumably trust to handle the webcam data they send over in real time.
