This is Doctor Who fan art (artist not known) featuring the character Zoe Herriot enjoying the time rotor in the center of the Tardis console. Amusingly, Wikipedia describes the time rotor as “a moveable column … in the centre [of the console] that bobs rhythmically up and down when the TARDIS is in flight, like a pump or a piston.”
