The best display eventually steps aside so the object can explain itself.

Good presentation knows when to stop. Lighting, framing, and a bit of context all exist to get someone to look properly, and once they are looking, anything more starts competing with the thing itself. The same is true of introductions, packaging, and the way you talk about work you care about. Past a point, more explanation is a lack of confidence in what you are showing.

Set something up well and then stop talking. Let the silence do its work, and notice how often a person needs only a moment alone with the thing to arrive at what you were going to tell them.
