But does it have a bar in the center? (Yes, it does, in fact, but maybe the wrong kind.)
The Galaxy Garden is an interesting idea. Artist Jon Lomberg put it together to give people a sense of the structure of the Milky Way. There's a fountain in the center representing the supermassive black hole at the heart of the Milky Way; it's (the black hole, not the fountain) currently not active so maybe a drain would have been better than a fountain.
Still, this looks pretty cool, and if I'm ever in Hawaii I'll have to check it out!
