GC is quirky, to be sure. I do hope this gets cleaned up as time
goes on. The LONG list of reserved names is one of my pet peeves.
I really, REALLY wish there were advanced preferences to manage
reserved names in GC.

Anyway, I have a bunch of physics-related files posted here:

<http://web.lemoyne.edu/~craigda/Physics/Sims/Files/filelibrary.html>

that I use as live demonstrations in my courses. I just finished up
a couple of reflection/transmission demos that are there now. The
files in general don't come with a ton of explanation, and most of
them are capable of showing a wide range of aspects of the physics in
question that are switched off when you first open the file. But if
you know the relevant physics, it should be possible to figure out
what most of them can do. (And I'm happy to answer any questions if
folks have them. Though perhaps not quickly...)
