 === Actors and Far References ===
+In AmbientTalk, concurrency is spawned by creating actors: each actor is an autonomous processor. AmbientTalk's actors are based on the [[Wp>E_programming_language|vat model]] of the [[http://www.erights.org|E programming language]]. In AmbientTalk, an actor consists of a message queue (to store incoming messages), a thread of control (to execute the incoming messages) and a number of regular objects that are said to be //hosted// by the actor.
+When an actor is created, it hosts a single object which is said to be the actor's //behaviour//: it is the "public interface" to the actor. The object that created the new actor gets a reference to this behaviour object, such that it can start sending messages to the new actor. An actor can be created in AmbientTalk as follows:
+<code>
+def a := actor: {
+  def sayHello() {
+    system.println("Hello World")
+  };
+};
+</code>
