OMG, that was AMAAAAAZING! I would give an arm to have my flat modeled like that, in such a fantastically small area, too! It has to be interesting living in that type of space.
Although I wonder how it would be like to have to remember which panels to move to get from your bedroom to your bath in the morning... you have to be extra alert lest you find yourself pulling the wrong panel in case of an emergency!
