About the question: I have an intermittenly
over-active God-module.
A strange thing happened to Benvenuto Cellini.
He looked at his shadow over wet grass
not long after sunrise, or before sunset,
and he noticed a shiny halo (!)
around the shadow of his head.
The sixteenth century Italian artist
of course believed that the halo was
a sign of God and a proof of his genius!
This halo is called the heiligenschein,
and is due to the brightest light return
ocurring at the antisolar point.
It is caused both by the reflection of
the sun's light from the far side of the dew
drops, and by the fact that you are able to see
illuminated grass stems which would be
masked from view from any other direction.
