Alright, answering questions. The white thing on the floor is a discarded long-sleeve white turtleneckish shirt, which I didn't really put much effort into. The 'headboard' is a pillow propped up against its end, on the wall, something which I do often to comfort myself when reading a book.
Being post-modern, I wanted to have elements of technology in with the sort of bland-ish hotel room, so the white 'ghost' brick is supposed to be static from a TV channel. Unfortunately, there's no static color in BL.
The grey object is a ceiling-mounted projector for the hologram TV screen.
