Hybycozo is a series of three fantastical golden polyhedrons. Made in laser cut steel, patterns create subtle rigid embroideries, reminding scientific drawings
Polyhedrons Tesselations
Making the 5 platonic solids (tetrahedron, cube, octahedron, dodecahedron and icosahedron) from solid wood using miter saw / table saw. At 4:29 the angle is ...

In my previous post on 2D & 3D Stellations we had seen that the Tetrahedron and Cube have no possibility of stellation, and that the Octahe...
You may or may not have enjoyed learning geometry, but now is the time to cast aside your emotions, and delve into this stunning project! Don't panic when you see the diagrams, it's really quite simple, and once you get...
I'm a programmer looking to create a 3D model of a Floret Tessellation of a sphere, like the one in this picture Class III 8,11 floret planar net (source) If anyone could point me in the right
This has the twelve regular pentagons and twenty regular hexagons of a truncated icosahedron (most familiar to the world as the shape upon which most soccer balls are based), but also has pairs of trapezoids in "bowtie" configurations. I discovered this polyhedron using Stella 4d, which you can try for free at www.software3d.com/stella.php.
All of these polyhedral images were created with Stella 4d, software you may try for free at http://www.software3d.com/Stella.php.
To begin this, I used Stella 4d (available here) to create a zonish polyhedron from the icosahedron, by adding zones along the x-, y-, and z-axes. The result has less symmetry than the original, but it is symmetry of a type I find particularly interesting. After making that figure, I began stellating it, and found…

The 110 faces are: sixty irregular pentagons thirty elongated, irregular hexagons twenty hexagons which are equiangular, and nearly equilateral as well Created using Stella 4d, available at http://www.software3d.com/stella.php.
If one starts with a cuboctahedron, and then creates a zonish polyhedron from it, adding zones (based on the faces) to the faces which already exist, here is the result, below, produced by Stella 4d: Polyhedron Navigator (software you may buy or try at http://www.software3d.com/Stella.php): The hexagons here, in this second image, are visibly irregular.…
This is the rhombic dodecahedron, the dual of the Archimedean cuboctahedron. While the rhombic dodecahedron has 12 faces, there are many other polyhedra made entirely out of rhombi, and most of them have more than twelve faces. An example is the rhombic enneacontahedron, which has two face-types: sixty wide rhombi, and thirty narrow ones. It…
The 182 faces of this polyhedron are 12 regular pentagons, 20 equilateral triangles, 30 regular octagons, 60 rectangles, and 60 kites. I made this using Stella 4d, which you can find at www.software3d.com/Stella.php.
To begin this, I took an icosahedron, and made a zonish polyhedron with it, with the new faces based on the zones of the existing faces. Here's the result. Next, I started stellating the polyhedron above. At the sixth stellation, I found this. It's a true zonohedron, and the first polyhedron shown here is merely…
This polyhedron is chiral, meaning that (unlike many well-known polyhedra) it exists in "left-handed" and "right-handed" forms -- reflections of each other. These "reflections" are also called enantiomers. I call this polyhedron "sixty and sixty" because there are sixty faces which are irregular, purple quadrilaterals, as well as sixty faces which are irregular, orange pentagons.…
