This is one of many ideas I've been trying to come up with lately to make a tree-based community that includes large, tall trees, a sense of fantasy, and still gives them enough horizontal space to walk around on and doesn't put them so high up that the force of wind blowing them off the tree would be a risk. Also the higher up on a tree you are the more the tree will sway in the wind, and I don't want them to get motion sickness everytime the wind blows.
