Sure. I for one have a huge weakness for this kind of tech, because it's an archetypal hack - a clever trick to pull something out of a system, whether the system likes it or not.
It's also interesting because it's deeply grounded in reality. It's no gluing crappy APIs together to solve a "problem" twenty layers deep in someone's convoluted business shenanigans. It's using reflected light to learn about mechanical vibrations at a distance, to show that the information is there, despite what you'd hear from people who don't comprehend how reality works. It's a nice reminder that everything that happens interacts with everything around it, and information about it spreads out at the speed of light. Most side channel attack are like this, which is why I find them interesting.
