I have a bit of a fetish for shows that feature some sort of non-human vision. I even like the cheesy computer overlay of Terminator-vision and the pseudo IR of Predator-vision, but what I really like are attempts to show how things look to different animals, like how bees see color (they can see ultraviolet) and shape.
Coral reefs and their inhabitants look like a riot of colour to human eyes, but how do they look to the organisms that actually live there? A recent new scientist article argues that what to us looks like vibrant contrast may be camouflage. The article also explores some of the other reasons for fish coloration.
I enjoy anything that helps me get my head around the experiential life of the non-human world. Differences in colour perception seem like a minor thing, but its amazing the difference it makes in what is noticed.
