I'm sitting on the floor. There's a very wide desk by the wall, and a good chair too, but sometimes it's nice to just sit on the bare wooden floor because it changes everything quite dramatically. From this low, the perspective is different than usual. As are the tactile sensations, obviously, and the smells too: the floor is hard and there's a faint whiff of dust down here. Put together, these changes in perception make it feel like a rather different room. No longer my office but its bizarro twin.
I would not know this interesting version of my office if I weren't willing to forego the comforts of my cushioned chair and sit on the floor from time to time.
