Students want to be able to go on a ride, a la Fantastic Voyage, and at the same time manipulate the objects they view in three dimensions. Having the animal and its parts alive and working would be exciting, some noted, although Nancy wouldn't like this, because she doesn't want to see blood. She would prefer a cartoon. Closeups are important, but not microscopic closeups. They want to be able to stop at any point, look around and get a description with a map showing where you are and where you've been.
Students like to play detective.
They also like scoring, and the option to work either by yourself or with a partner. They want to be able to backtrack, and have a great deal of control over all aspects of navigation. One student suggested having a table of drugs you can administer the creature to see what happens.
