. . . Brought me to this stellation of a convex hull of something or another . . . and it looks much like the polyhedral tattoo on my left wrist.
They aren’t a precise match, though. Here’s the tattoo for comparison:
The tattoo’s polyhedral design was also originally generated with Stella 4d (see http://www.software3d.com/stella.php), by multiple stellation of the dual of the rhombicosidodecahedron, and then turned into my tattoo by Nicholas Pierce at The Golden Lotus in Sherwood, Arkansas, USA. Their website is at http://goldenlotustattoos.com/.
It took some time for me to find the significant difference in the two polyhedra. Can you spot it? (Stop reading now if you want to solve this yourself.)

To find the difference, look at a single facelet — any of them. They are all non-convex pentagons, with larger and smaller “wings,” and, in one of them, the smaller wing has a triangular shape (rotating above), while in the other (the tattoo), it comes to an edge, rather than a point — more resembling a convex quadrilateral than a triangle. That’s the major difference I have spotted.
