So are these Target stick-ups toys or what? How does
Target sell them... I mean to whom for what purpose?
Seat shakers?

Fun stuff.

There was a Decware design floating around which I tried
to track down. The membrane was small and desktop size
but, you know, look like they come from the future.

So who's going to post the first "This is a good place
for a stick-up" article?

If cardboard is good, is Masonite better?

As an aside, I have been wracking my brain for the issue
of audioXpress in which they show a Cornu-type spiral horn
construction project. I have the mags... but there's no
multiple year index. I started to look for it one day and got
distracted by all the other neat stuff in the old mags.

Teh Cornu spiral horn is another design to fit thin
and close to the wall.
