Disappointed to see the dots around it all appear to be the same spacing. They should be at different spacing, corresponding to strobe sync with 50 and 60 hz mains and 33.33 and 45 RPM. Hence four rings with different number of dots around the perimeter.

They are at different spacings. If you follow two rows of dots around, they fall in and out of sync with each other.

Now someone has to go there and drive around it at 33 1/3 rpm at night with a strobe light set to 50 Hz.
