Hello Jeff. I just saw the first 3D interactive surface of your list below
(my connection is too slow right now) and I can see that your surface is
totally dark from below. A simple improvement is to add additional light
sources so that the part below can be seen, as explained in this link:

There are more things that can be done with LiveGraphics3D, not only rotate,
you can create graphs that can be manipulated by the user, and here is a
very simple example:

I have written a small LiveGraphics3D Tutorial. It is in Spanish; however it
might be useful for your students/assistants because it has many graphs and
very little text:

I have seen your site before and it has many great graphs. I use some of
them in my computer's wallpaper; they change every 15 minutes thanks to a
program called Webshots:

Asunto: [mg60939] Visualization site updates

   I've begun adding some new functionality to my visualization site.  A 
few people have requested the ability to be able to interact with the 3D 
graphics in real-time.  I decided to try using LiveGraphics3D by Martin 
Krauss on several of my examples.  Some of the examples are not 
appropriate for real-time interaction as the render time was too long. 
I picked a few of my 3D visualizations that were more reasonable.  For 
those examples that are interactive, they are often rendered at lower 
resolutions to keep loading time down.  I'd would be interested in 
hearing your thoughts on whether this is useful where appropriate.  Here 
are the examples I currently have:

I have also added a new visualization (non-interactive) that uses 
Mathematica to visualize molecular structures in the protein data bank 
format.  This particular animation shows an insulin molecule with 14,940 
atoms in it.  To keep the render time down, I used 3D points instead of 
spheres which unfortunately means no lighting effects:
