I once heard someone say, "everything changes except the Sea."  It instantly entered my long term memory and comes to mind quite often.  On the other hand, does anything change more frequently than the sky?  Is this constant change one of the reasons why people (well, at least myself) love to behold the sky?  Is this the reason why the sky is so often photographed?  Or is the sky just the most beautiful thing about Earth?

Just 16 minutes earlier, the sky looked like this that evening . . .
