Here is yet another, compact version, with the generics syntax:

    public static IEnumerable FindLogicalChildren(DependencyObject obj) where T : DependencyObject
    {
        if (obj != null) {
            if (obj is T)
                yield return obj as T;

            foreach (DependencyObject child in LogicalTreeHelper.GetChildren(obj).OfType()) 
                foreach (T c in FindLogicalChildren(child)) 
                    yield return c;
        }
    }
