Design can be art. Design can be aesthetics. Design is so simple, that's why it is so complicated.

Preczewski, Stanley C. and Fisher, Donald L. (1990): The Selection of Alphanumeric Code Sequences. In: D., Woods, and E., Roth, (eds.) Proceedings of the Human Factors Society 34th Annual Meeting 1990, Santa Monica, USA. pp. 224-228.

Maintaining secure radio communications in the armed forces places an especially heavy cognitive load on all involved personnel. For example, in the Army each individual must memorize on a daily basis at least three new five character codes. The current Army code consists of the sequence letter-digit-letter followed by the sequence digit-digit (LDL-DD.) Research on paired associate learning suggests that recall could be improved by using either a letter only stimulus pair (LLL-LL) or a letter-digit stimulus pair (LLL-DD). An experiment was run to test this hypothesis. Recall for the experimental letter-digit code was over twice as good as recall for the current code.
