I think I've heard of MC Escher.

Watched the first episode of Castrovalva earlier. It seems vaguely familiar, but in these days of YouTube stockpiles of small clips, it's hard to be sure if I've ever seen the entire episodes. Time will tell.

As I'm watching, they haven't gone to planet Castrovalva yet, but the weird and irrational topology of the TARDIS interior is a part of the plot already. The newly-regenerated Doctor (maybe that's why I bought this particular series) and his companions wander at length through the interior, marking their way with yarn and bits of clothing. Naturally, they find their goal will still mostly clothed.

This reminds me of yet another distinctive feature of the latest incarnation: The TARDIS becomes more of a character in its own right, at one point even...well, spoilers. But the bigger-on-the-inside and shifting topology schtick gets worked effectively into a lot of action deep in the bowels of the machine.
