Just stumbled upon these images of a mirrored treehouse situated about 60km south of the arctic circle in Sweden.
My my, how fantastically beautiful. The architects have even coated the surface with a lacquer that is visible to birds to prevent them from flying into it.
I then went feverishly looking for more cool ones and I'm now nostalgic for a treehouse that I never even had. The best I could muster when I was a kid was a scaggy piece of rope and hidden multi-bag of Twixes. Enjoy.
