Magic Box

I've been repacking and packing my room-- partly because it's small and I have to pack stuff up from time to time to make room, and partly because I don't know where I'll be or what's happening next.  I couldn't get this box down, but that's okay.  It seems just fine where it is. 

No, nothing is holding it up but the bed and wall.  And it's holding up my lamp and stuff.  Pretty neat trick!
