The following are the universally fundamental laws of literary communication: 1. one must have something to communicate; 2. one must have someone to whom to communicate it; 3. one must really communicate it, not merely express it for oneself alone. Otherwise it would be more to the point to remain silent.
- Friedrich Von Schlegel
For displays of any sort to be effective, they must first capture the audience's attention. Then, as a general rule, communicate their message in five seconds or less.
