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).
