Yes, the surprise is not so much that it happened, but that the photographer was there at the one(?) precise date and time.
Like a stopped clock, its precisely correct, once each period! Makes a great picture, regardless.

I would have thought it should be very simple and not a freak. As long as the sides of the post are parallel to the paving slabs and the sun is exactly south (or north if you are in the southern hemisphere), at twice a year this should be the result. The dates would depend on the height of the post. Although, I think it should work even if it isnt due south, just when the sun is directly behind the post and the right height.

Hello, This freak shadow alignment is featured on ASAP Science's Facebook page. The question is how to design something similar. Anybody? Dan Uza
