-## Animations
-
-Most objects that are animated are actors, and most properties used in animations
-are animatable, which means they can use implicit animations:
+## Getters, setters, and Tweener
 
+Getters and setters should be used when you are dealing with an API that is
+designed around setting properties, like Tweener. If you want to animate an
+arbitrary property, create a getter and setter, and use Tweener to animate the
+property.
 ```javascript
-    moveActor(actor, x, y) {
-        actor.ease({
-            x,
-            y,
-            duration: 500, // ms
-            mode: Clutter.AnimationMode.EASE_OUT_QUAD
-        });
-    }
-```
-
-The above is a convenience wrapper around the actual Clutter API, and should generally
-be preferred over the more verbose:
-
-```javascript
-    moveActor(actor, x, y) {
-        actor.save_easing_state();
-
-        actor.set_easing_duration(500);
-        actor.set_easing_mode(Clutter.AnimationMode.EASE_OUT_QUAD);
-        actor.set({
-            x,
-            y
-        });
-
-        actor.restore_easing_state();
-    }
-```
-
-There is a similar convenience API around Clutter.PropertyTransition to animate
-actor (or actor meta) properties that cannot use implicit animations:
-
-```javascript
-    desaturateActor(actor, desaturate) {
-        let factor = desaturate ? 1.0 : 0.0;
-        actor.ease_property('@effects.desaturate.factor', factor, {
-            duration: 500, // ms
-            mode: Clutter.AnimationMode.EASE_OUT_QUAD
-        });
-    }
+    var ANIMATION_TIME = 2000;
+
+    var MyClass = class {
+        constructor() {
+            this.actor = new St.BoxLayout();
+            this._position = 0;
+        }
+
+        get position() {
+            return this._position;

+
+    let myThing = new MyClass();
+    Tweener.addTween(myThing,
+                     { position: 100,
