One of the last (and best) books I read was "house of leaves". About a house with inside spaces larger then the actual house was, and these were slowly changing in size as well, forming a cold, dark, shifting labyrinth with rooms so big they were devoid of echos and flashlights didn't reach the walls. Expeditions were set up to explore the insides and several got lost in the infinitely large shifting spaces. The book itself was in fact written as a kind of labyrinth with certain blocks of text written upsdide down or even through the depth of the pages (
wikipedia example).
All this dimensional weirdness reminds me of the hitchhikers guide to the galaxy. I think it was the secret ruler of the universe who had his little shack built inside out, so that the entire universe was actually inside and the small space that his shack enclosed was outside.

Love to know the name of that book rdc, it sounds interesting!
