 It is easy to create your own animation curve by passing in the X and Y components of two control points of a cubic Bezier curve (as shown in __Example 4__). Using Bezier curves is a common technique to create smooth curves in computer graphics and they are widely used in vector-based drawing tools. The values passed to the cubicBezier method control the curve shape. The animation speed will be adjusted based on the resulting path.
 
-For help finding the `cubicBezier` values you need for your custom animation timing function, use the visual tools on [cubic-bezier.com](http://cubic-bezier.com). Once you find an animation path you like, simply copy and paste the cubic bezier values and paste them in the `AnimationCurve.cubicBezier` function. Their should be four numbers (X,Y coordinates for each of the two points in the animation).
