Interesting indeed, AE.
Now here's a question that would begin all kinds of discussion around the subject, I bet: So if they ever did come out with this material capable of altering the optical wavelengths, how would we prove that it works on deer? You know, what with their different rods and cones and all, combined with their supposed ability to see ultraviolet images.
No problem proving this one, light is light. Ultraviolet rays are just a higher wavelength of the light we can see. Rods and Cones are the same as well. Theydon't have Cones(or if they do not very many) becuase they allow you to see color. They do have Rods and a lot more then we do which allow them to seein low light conditions and at night.
