It is very interesting, aesthetically pleasing, and also anti-copy for QR codes.
To use it, you must select the second "Dots Options" as the default.

(At first, I chose option 1. I was a bit annoyed that all four images were not usable. When I went back to see everyone's comments, I was not very satisfied. When I went back to check the home page, I saw that some images were usable and some were not scanned. Choosing option 2 again is fine.)
