Found this video featured on Yahoo! of the sweetest tree house I've ever seen - spiral staircase, working lights, electricity, carpet, deck and a whole lot more. I never really longed for a tree house as a child, but if I thought it would be like this house, I would have begged for one!

Now I know there might be some property restrictions, but hell, maybe we could help them refinance this "mansion" if they ever need us...
