Starting with the idea I had with making canopies—by hanging thinner branches from above rather than supporting from below—I came up with a way to make a 3D test of that idea. I started by making guard-rail posts around the perimeter of the elevated trunks that people walk on. Working upward, many of the posts would have a rope to anchor the bottom of a branch. On the lower elevated level, the tips of the branches would have a rope tied to another branch which would have holes to hang leaves with messages; the upper level would only have the main branches to hang leaves. The tips of all these branches would be anchored from above with ropes to the next level up.
This way, the branches will sway with the wind with a great deal of flexibility. Further, for any that break, the rope or rigid branch can both be replaced on the Playa. If the branches had been rigidly attached from below, flexing of the branches would be difficult to achieve, and they would be prone to permanent breakage.
For now, I only rendered the first set of branches, omitting the forks on the lower elevated level. I also omitted any anchors, simply placing the branches how I would like them to appear.
