I could use it to lay out my living room for the movers. Then they could see the layout I want for each piece and then replace the layout with furniture as it's unloaded. As I'm setting this up, I can get a sense of how each furniture piece might fit in my space. On a smaller scale I could use it to place objects where I was thinking of putting a new piece of furniture and then spend a week living with the space carved out before I buy the piece. If there were a smartphone app that took dimensions and then supplied assembly instructions it would be golden.
