I'm brand new to InterViews, and I'm looking for simple iv demonstration 
programs.  I've examined and built a number of the applications in the
ibuild-samples directory.  I'd be pleased, however, if I could find
a sample program which is closer to the sorts of programs I want to build.

Here's what an ideal example program would look like:

    -  display a previously-created image
    -  offer a variety of menus and mouse options to manipulate the image
        (zoom, pan, perhaps dynamic modification of the color map)

Can anyone point me towards a program like this?

Here's a related question: a year ago I learned quite a bit about Motif
for a project I was then engaged in.  I benefited enormously from having
two excellent books (one by Douglas Young, one by Thomas Berlage).  Both
of these books teach by example, and after working my way through the 
two I had a reasonable grasp of how to use Motif.  

Is there any hint or rumor that a similar book will be available for
InterViews?

Thanks.
