That was bit was done in the Tom Baker era (IIRC). Although, the effects weren't as good then. :-)
Whatever happened to Davros. I completey forgot about him. Wasn't he the Dalek leader for forever?
Here's one more thing that the new doc keeps mentioning that I'm not getting...when did Gallifrey and the Daleks kill each other? Is the Doctor hinting at a new, up coming story, or did I miss this story from a long time ago?
