The kaleidoscope concept is interesting and the industrial design is neat.
Production could be challenging keeping those little mirrors aligned.
While this type of DOF manipulation in post will never look as good as when the effect is captured optically, using either a longer focal length, a wider aperture, closer subject distance, or tilt... the advantage lies in the speed of taking the image when you don't have time to set up the shot properly. You just have to live with the "uncanny valley" effect as it's the best that software can do. Maybe if the depth map was deeper in terms of bits, the blur tool could smooth out the transitions better... I still wouldn't want to print anything from it on a large scale.
I didn't see a price, but because the final resolution is effectively halved, you really need to use a 40+ megapixel camera to end up with something you're proud of. The math of this type of lens being worth it in the hands of a good photographer is:
$[40MP body & K lens] ≤ $[20MP body & TS lens]
