Ah ha! I should have thought about that for a few more seconds before
asking because the whole point was because this was another screwy
topology and I forgot to look for the screwiness.

I did briefly look at the sorts of paths that the petals can take and
they are quite interesting. Alternating LLRRLL, etc. can create a
straightish ziz-zag path that miraculously involves all faces except
those two odd ones, whereas if you start with one of those odd faces you
hit a dead-end at the other one! Fascinating.

And yes, they do look a lot like streams of bubbles filling the air. I
like it!
