Very, very good point, and one I'd forgotten. For those who haven't
dug into Geomview, I should briefly explain the apparent contradiction
between what I said before and what Paul's saying. Geomview is, indeed,
driven by a simple Lispoid language. However, the code in that language
can be generated "on the fly" by external programs (and, I gather,
usually is). So, for example, you can have a C program communicating
to Geomview through this Lisp, sending Lisp commands and receiving
data in that form.

As I said, excellent point. This may well be the best medium between
the various arguments: a nice easy-to-interpret language, which you
could send statically *or* generate dynamically through outside programs.
It would probably satisfy both our short- and long-term needs decently
well. I like it...

And Mike, if this is what you were saying, and I wasn't understanding
you correctly, my apologies...

Once again reminded that, although I
don't adore OOGL, I *do* think Geomview
has some very clever ideas...

anything else."
