Greeking

Greeking is a style of displaying or rendering text or symbols, not always from the Greek alphabet. Greeking obscures portions of a work for the purpose of either emphasizing form over details or displaying placeholders for unavailable content. The name is a reference to the phrase " Greek to me", meaning something that one cannot understand, so that it might as well be in a foreign language.
