Above is one of many samples from the Flickr group Security Patterns, which documents the patterns designed to prevent ne'er-do-wells from peeking at the contents of envelopes. It's like orgami patterns, but designed to be willfully obtuse. I love it.

I found this very wave pattern inside an envelope I've been carrying around for decades. It set me of looking inside envelopes! I'm having fun making cards with the scraps.
