Settings: Formula 37, Render 8, Julia Mode, Color 13-2 modified, Transform 3 arctan, Iterations 10.
These are the same settings as the previous one, Paper.loo. This one is a detail from a Julia mode setting. Julia mode when used with arctan often produces radically different images from the plain arctan setting. Flat sheets become fans of flower petals and in this case something that looks like a crescent moon cut out of paper.
