affirmative, i see it pass by about every year since 2013, i still look at them with as much amazement as i did in 2013. A reverser ring for a e.g. 50mm to do macro is quite common in photography. Extender rings work quite nice too, though depth of field becomes mega-shallow, so for any significant object, you will need to resort to image stacking to get a properly focused subject.
