Vortex loop

The vortex loop. (GAME: Attack of the Graske)

The vortex loop was a component of the Doctor's TARDIS. (GAME: Attack of the Graske)

Behind the scenes

In Attack of the Graske, the vortex loop was operated by the player at home with either the digital remote control or a computer mouse which has been temporarily linked with the sonic screwdriver. If the player chose incorrectly, the Tenth Doctor, who was busy elsewhere in the TARDIS tracking a Graske, picks it out for them.
