When the eye become a spy

Dear Friends
from the many suggestions of Paolo Vigevani in his Quando l'occhio diventa una spia (When the eye become a spy) http://scaviscaligeri.comune.verona.it/nqcontent.cfm?a_id=46239 
in Verona, I certainly prefer that of the play of the light, which through the reflection http://en.wikipedia.org/wiki/Reflection_(physics) and refraction http://en.wikipedia.org/wiki/Refraction highlights the nature. As you can see from the images, the play of the light bring insignificant and trivial subjects directly to the attention of the viewer. Please, let me have your feed back.
Salutations
