From Tardis Wiki, the free Doctor Who reference
A Time-Space Visualiser was a device that allowed the operator to view any event in history. The First Doctor and his companions used it to observe Queen Elizabeth I and Francis Bacon meeting with William Shakespeare, Abraham Lincoln delivering his Gettysburg Address and the Beatles performing "Ticket to Ride". The Visualiser later showed them the Daleks launching their time machine on a mission to exterminate them, which let them buy some time.
