How does it move
You know the answer
With wonder and magic and lots of code? :D
I do have to say though that I really like the way the build is integrated into the island, which kinda gives me a neat idea.
I think its starting to fill out and I like all the various assortments of buildings. Those vines are really cool too.
The only thing I dont particularly like is that ramp pattern you use from some of the walls although that's only a minor thing.
This would be a cool community build. I know Heedicalking did something like this once but it'd be cooler if all the islands bridged together, more of a collabortive effort. Like Badspot's Block Party with more floating islands.
