In web design circles the little stacked three line graphic that you often see on websites to denote a clickable menu is usually called a hamburger (or just burger) icon. We call it that because it sort of looks like how a computer would display a minimalist hamburger. I adore that in the bottom navigation area of kottke.org, he has one that — instead of opening a menu, as you’d expect — takes you to an archive listing of all the posts he’s ever made referencing… hamburgers.
