Blinking an object

Is there any easy way to blink an object?

I suppose you could toggle the Visible property in a Timer.
You’ll want to temporarily set the SkipsUndoManager property to true, first, if you are using an UndoManager.
Alternatively you could change the color of some shape, or replace the Image by changing a GoImage.Name or .Index.
Or you could add some object to the GoView (actually to one of the GoView’s layers) that would surround the object. Since you would be changing the view instead of the document, you wouldn’t need to set SkipsUndoManager temporarily.

I will try “toggle the Visible property in a Timer” first, see how it looks. Thanks.
