You know what ammolite is, right?
It's the fossilized shell of a squidesque beastie that lived in the late Cretaceous (IIRC) period and which died out with the dinosaurs. The shells of those guys were apparently made of something very much like the stuff that makes pearls, but the fossilizing of their shells makes them all opalescent and gorgeous and rainbow-glittery.

What to do on your day off.

My head, let me show you it.
A patient with a split brain, when shown an image in his or her left visual field (the left half of what both eyes take in, see optic tract), will be unable to vocally name what he or she has seen. This is because the speech-control center is in the left side of the brain in most people, and the image from the left visual field is sent only to the right side of the brain (those with the speech control center in the right side will experience similar symptoms when an image is presented in the right visual field). Since communication between the two sides of the brain is inhibited, the patient cannot name what the right side of the brain is seeing. The person can, however, pick up and show recognition of an object (one within the left overall visual field) with their left hand, since that hand is controlled by the right side of the brain.
The same effect occurs for visual pairs and reasoning. For example, a patient with split brain is shown a picture of a chicken and a snowy field in separate visual fields and asked to choose from a list of words the best association with the pictures. The patient would choose a chicken foot to associate with the chicken and a shovel to associate with the snow; however, when asked to reason why the patient chose the shovel, the response would relate to the chicken (e.g. "the shovel is for cleaning out the chicken coop").
