Space-time projector
From Tardis Wiki, the free Doctor Who reference
A space-time projector was a piece of Time Lord technology that allowed the user to see all of time and space. Components of the space-time projector included the relativity map and a temporal chamber. Kotris helped the Dalek time controller build a space-time projector in his plan to wipe out the Time Lords. Kotris' space-time projector was erased from history when Straxus was killed, and Kotris never had existed to build it. (AUDIO: X and the Daleks)
