How do I programmatically run an animation?

You can progrmatically run an animation by loading the Storyboard into memory and calling it's Begin() method.

For example:

Storyboard sb = (Storyboard)this.Resources["LookUp"];

sb.Begin(this.ellPupil);

In this code, the name of the Storyboard is "LookUp", and in the call to the Storyboard's Begin() method, the object to which the animation applies is passed.
