PowerPoint Zen > Gates v. Jobs

"In the world of PowerPoint presentations, you do not always need to visually spell everything out. You do not need to (nor can you) pound every detail into the head of each member of your audience either visually or verbally. Instead, the combination of your words, along with the visual images you project, should motivate the viewer and arouse his imagination helping him to empathize with your idea and visualize your idea far beyond what is visible in the ephemeral PowerPoint slide before him. The Zen aesthetic values include (but are not limited to):

Simplicity [kanso]
Subtlety
Beauty , Elegance
Suggestive rather than the descriptive or obvious
Naturalness (i.e., nothing artificial or forced) [shizen],
Empty space (or negative space)
Stillness, Tranquility
Eliminating the non-essential
