Show HN: Homemade rocketship treehouse – hardware to custom OS
This is probably a completely unrealistic goal for a wide variety of reasons, but it would be amazing to have something like this in a public park.I could also imagine going on tour.  Like, you get permission in advance from some random park in some random city, and you just set it up with no public announcement and just see what happens.  I mean, when I was a kid I'd think it was awesome if some random spaceship just suddenly was there, and then a week or so later it was gone.  Even if it's clearly not a real spaceship, it'd still have been a great experience.
