Morse Code

Ah, hiding in a little cove, sending flashing light signals across a harbor to a hidden viewer. I'm not doing that, but it would be neat to be able to if it was ever needed. My point? Morse code is pretty cool.

I can't help loving Morse code, because it's made with dots and dashes. Because of this, you can signal it with whatever you want. You can use a light. You can use sound. In a book that I read, one character even did it by flicking his eardrum, as if he were fidgeting. And I'm sure some readers have heard that story of the guy who was trapped on a ship, and was rescued because he blinked out "torture" in Morse code with his eyelids.

Er, sorry for the morbid story, but the point is, if you can come up with a system with one thing representing a dash and the other a dot, then you can use Morse code. And that makes it awesome.
