I've been involved in a system that used morse for short error messages.
Unless you actually know morse it is completely hopeless.

With two leds next to each other you should be able to generate
a lot of easily identifiable patterns by repeating separate 4-bit
patterns (in sync) on both leds (at about 2Hz update).
