All true. But how often have you seen anyone do any of those?

Ed, as the words of the song go, "You say tomato, I say
potato" (well, close enough for you to get the point).
There are all kinds of things you can do with whisper dishes. You
can play around with finding how far off axis you can get and
maintain projection and reception; you can play around with how far
away from the focal point works; you can play around with with
happens if people get in between the whisper dishes. you can 'send'
hidden messages to people walking by, you can have fun by finding out
how soft or loud you have to be - the point is, the opportunities
don't have to be as limited as you imply.
One of my earliest memories from a science center/ or perhaps from a
pavillion at the '64 Worlds Fair, is the excitement I experienced
discovering the whisper dishes on display. It obviously made a
pretty big impact on a nine year old.....
