I love things that hide things. I especially want that bathtub and the vent/safe. The TV hiding all the other electronics is a great idea, but I'd imagine there'd have to be some kind of sensor in order to work the other stuff.
A cool idea on using the space of the corner cabinet ! With these shelves, you can organize, see what's in it and not have to get down on your hands and knees if there was a lazy Susan in the space. Down side--- no hide and seek space.
