3. Evernote
Elephants are known for having impressive memories, including their ability to remember both faces and events. It’s for this reason that Evernote, a note-taking application, uses an image of the animal as part of its logo. The corner of the elephant’s ear, moreover, is folded over — in the same way that people often fold the corner of a page in a book to make note of what point they’ve read up to.
