Pete,
I usually stand aside when you weigh in with your insight but this time there are some problems with the picture that are not explained away. Only after you mentioned it did I see the white object (dove?) in the disk. It certainly is NOT the centerpiece of the picture. If it is the underlying theme it would not almost be hidden. Given it center location and size relative to the disk it more resembles and insignia than anything else.
I have seen many representions of the Holy Ghost and the sun breaking through the clouds. it is a popular theme. A large mechanical disk is not. The dove is always prominent and the sun breaking through diffused its rays pretty randomly.
Not this picture. And the automatic interpetation of the picture now speaks for itself. Lots of people see apparitions where none exist but this is different.
