Have you seen the Galaxy S3 lockscreen? There is not an image that moves. They had to remove the visual feedback which is an obvious addition to Nenode's slide to unlock. But apparently it is still not enough for Apple.
No, I haven't seen it and in that case (based on your description and my very quick reading of the claims) I would hope and expect it to be found not to infringe. That is a separate issue from whether it is valid (except that both should be judged under the same understanding of the claims - narrow or broad).
