Since a large portion of this is the 3d impression the user has, I'd like to request a stereo view option. Anyone who can see a magic eye image can use them, and they've been popular in other projects that involve visualizing large molecules. I don't think the render time would be noticeable, either. Just don't forget that there are two ways to display stereo view pictures- cross-eyed and not, and many people can only use one or the other.
