Time-Space Visualiser

A Time-Space Visualiser (also known as a Space-Time Visualiser) was a device that allowed the operator to tune in to any event in history.

The Doctor was given a Time-Space Visualiser by Tor as a souvenir. (DW: The Space Museum) After getting it working again, the TARDIS crew used it to observe Queen Elizabeth I and Francis Bacon meet with William Shakespeare, Abraham Lincoln deliver his Gettysburg Address, and The Beatles perform "Ticket to Ride". The Visualiser later showed them the Daleks launching their time machine on their mission to exterminate them. (DW: The Chase)

The Doctor later used the Visualiser to trace the origin of an alien spaceship fragment to the island of Saluta in 1934, creating a time bridge to that year. (MA: The Eye of the Giant)

Faction Paradox used a Time-Space Visualiser to forecast Fitz Kreiner's future, showing him an image of himself as Father Kreiner. (EDA: The Ancestor Cell)

Izzy Sinclair used the Time-Space Visualiser to play video games. (DWM: Happy Deathday)
