obsidian.loo

Settings: Formula 26, Render 5 Orbit counting, Color 13-4 modified, Julia Mode, Inside-Out.

If you load the parameter file to this one and press reset coordinates (zoom back to original starting point) you'll see something pretty uninteresting. I was surprised to find this object on one of the orbital "rootlets". I thought it looked like an Aztec sacrificial knife which has a blade made of volcanic glass; a material called obsidian.
