# A Non-Convex Polyhedron Made of 180 Kites

I just woke up, and found this waiting for me on my computer. Apparently, I made it when I was half-asleep, hours earlier. I made it using *Stella 4d*, which you can try for free right here. Its faces are 60 small red darts, and 120 large yellow darts.

# A 72-Faced Polyhedron

The faces of this polyhedron include twelve regular decagons, as well as sixty convex pentagons. I made it using Stella 4d: Polyhedron Navigator, which you can try for free at http://www.software3d.com/Stella.php.

In the image above, the icosidodecahedron’s final stellation is colored by face type. In the one below, I used “rainbow color mode.” Both were made using *Stella 4d*, which you can try for free at http://www.software3d.com/Stella.php.

I created this using *Stella 4d*, software you can try right here.

# A Faceted Truncated Icosahedron With 32 Faces
