My High School had one of those.  I don't know how it works, but we had
a great time peeling the metal strips out of books when we found them and
slipping them into peoples backpacks, etc.

When I bought The Connection Machine from B. Dalton's here in portland,
one of those things fell out.  It wasn't even attached to the book.
