This lovely sculpture is itself impressive, but what I found most noteworthy was that this mysterious photo was placed on reddit, and the hive mind of that community went to work tracking down information about it. One redditor even found a Google Street View image to confirm the location. This little house was built at a remote lake in the Altai Republic, Russia by a group of green living enthusiasts.
