with some op amps. If you want to play, there's an article in SciAm this month on building a chaotic "encryption" machine. It probably provides acceptable security if you use triple DES on signals prior to sending them.

That was smoke and mirrors by people who understand chaos better than they understand encryption. All it boils down to is a synchronised pair of (not very good) PRNGs. It's not a substitute for a one-time pad by a long chalk, which is how they seem to be using it. Basically they've just reinvented every schoolboy's exor encryption program all over again, this time with the latest 'chaos' buzzword thrown in to make it sound hip. Forget it. It's a dead end.
