This is only a test

So at the tail-end of my Double Leo Sister's surprise visit with her family, I was sitting in a Greek restaurant, feeling fortunate to have survived the three days with no emotional explosions. (Oh, there were explosions, but none directed at me, so I was all right, Jack.)

The painting below caught my eye, and I stared at it for a few minutes in disbelief, before asking the Jolly Not-So-Green Giant Brother-in-law if I were seeing what I thought I was seeing.

I want you to look at the painting before scrolling down. What do you see? Go on, I'll wait:

Ready?

My brother-in-law told me it was a blue door and two shuttered windows on a house of sand-coloured brick set into a courtyard.

I saw three dangling Tardises -- or what ever the plural of TARDIS is.

I sent the photo to the Resident Fan Boy in Hades. You can probably guess what he saw.
