“It goes ding when there’s stuff.”
Blink aired this day 9 years ago and was the first appearance of not only the Weeping Angels but also the device the Tenth Doctor (David Tennant) uses, built out of a portable tape recorder to detect temporal anomalies and to find others who too were caught by the Angels and transported to 1969.
Such a device was used again to seek out a Zygon disguised as Queen Elizabeth I (Joanna Page) in The Day of the Doctor.
