Two things to bear in mind:
1) I don't claim this to be a serious encryption device. It's just a _toy_
for spy-minded kids.
2) Re: the single key, these little panels will be spread around so thinly
for the forseeable future that more than two people at a time are unlikely
ever to use one together. And if they do, then they'll form a sort of
copycoder 'club'... i.e, it's a game for children and teens.
PS. There was a prototype also developed using variable key codes
(hexagonal, rotatable segements containing binary-numbered element
combinations) but there was no point - software encryption is so much
better. I expect this simple version to be more successful in the market
it's intended for...
