I saw this today when I was going to email and I just thought "what?!? That's nuts.." It's a pretty creative idea and crazy that the idea actually worked out and is a real "tree" hotel now. The Tree Hotel is all "green" and eco-friendly too.
Looks mad small but it's definitely a cool concept.
Here is an indoor shot of what it looks like inside.
Here's a link to where i read about it if you don't think this is real - http://green.yahoo.com/blog/guest_bloggers/56/almost-invisible-mirrored-tree-house-built-in-sweden.html
