Doesn't look like much. This is the cabin of Theodore Kaczynski, the "Unabomber". Kaczynski built the little hut himself and lived there for 25 years, going insane, writing in journals, and eventually writing long anti-technology screeds and building bombs to mail to technologists.
When they got the guy, they decided to take his cabin intact to his trial, so they could show the conditions he was living under to try to show that he was insane. Eventually Kaczynski pled guilty. For some legal purpose the cabin was kept around, but now it's no longer needed.
It was going to be dismantled, but the owner, a member of Kaczynski's legal team, was spooked when the event drew reporters. It'll probably wind up dismantled after all. Which is okay; what are you going to do, put it into the Museum of Bizarre Criminals?
