HyperMultiMedia - VRML97 Examples

It is not just HyperText,
And it is more than HyperMedia.
Technology gives us HyperMultiMedia.

I started this series of examples using the IndexedFaceSet tutorials from Chapter 3: Node Reference -- The Annotated VRML97 Reference 1997 by Rikk Carey and Gavin Bell. Gavin Bell had referenced this book in the comp.lang.vrml ng, so I had a look at it.
Above, the front figure is the simple shape, and the three blue figures are from the first example for normals.
The text (look the Key viewpoint) is a notation I am experimenting with as a relatively simple yet relatively complete method to describe the syntax. Any comments?
