Someone found this, and “liked” it, in my old Facebook pictures. I had forgotten all about it, until this happened. It is a mandala, made of rhombi, with nine-fold symmetry, made in 2010 with Geometer’s Sketchpad — two years before I started this blog.
To create the octagonal mandalas, I used Geometer’s Sketchpad and MS-Paint. I then projected them onto the faces of an all-but invisible icosidodecahedron, and created this rotating .gif image of it, using Stella 4d: Polyhedron Navigator, software you can try for free, right here.

These are “lost mandalas” I found on an abandoned Tumblr-blog which I started before making my transition to WordPress. The first three were posted there in 2012, and the next two were posted in 2013.
First, a cuboctahedron.
Next, its dual, the rhombic dodecahedron.
And, after that, the icosidodecahedron.
And finally, its dual, the rhombic triacontahedron.
All of these rotating images were assembled using Stella 4d, available at http://www.software3d.com/Stella.php.
