I remember seeing a documentary years ago about how insects see the world. For instance bees can see patterns on flowers we don't perceive. If that isn't cool enough. Dogs, cats and other animals can see the UV or ultraviolet colors that we can't see. Humans with lens removed due to cataracts and replaced by non-UV blocking lenses can see them too!
