These pictures were inspired by a Doctor Who episode: Castrovalva, which in turn refers to one of the prints made by the graphic artist M.C. Escher. The story tells how the Master sets a trap for the newly regenerated Doctor. In these pictures I have included all the Doctors plus their respective Tardises (have fun finding them!).
I also gave two different textures for the scene, one brick the other marble, just to see how they looked.
Enjoy!
