Roulette: Icon Index Symbol

Terrence W. Deacon summarizing Pierce in The Symbolic Species

No particular objects are intrinsically icons, indices, or symbols. They are interpreted to be so, depending on what is produced in response.

One example comes to mind: the figures designating public washrooms. In one interpretation they are an icon depicting gender formations, in another interpretation they indicate the facility is just behind the door and finally they can be interpreted as part of a symbol system.
