As optical illusions go it was one of the more spectacular, a little group of bright stars appearing to move along the night sky as if on a secret mission
while, of course, it was the low clouds that were doing the moving, scattered over my head by a wind from the east. And as hard as I looked I could not get the stars to budge again.
It was like the curious figure of the duck/rabbit...
