Golden Rectangle with Spiral...

I recently built a small golden rectangle piece that is kind of fun. Not sure if it's finished yet or whether it will maybe be incorporated into another project down the road… Above you can see where I'm cutting pieces of pre-curved steel to fit into each of the internal golden rectangles. Below is the finished (or not?) piece.

And here's a rust on paper deal I did with it before adding the spiral. Nice overlay shadow being cast by the open dodecahedron outside my shop:

A Beginner's Guide to Constructing the Universe

If, like me, you are remotely interested in numbers or sacred geometry, you simply MUST get Michael S. Schneider's A Beginner's Guide to Constructing the Universe, Harper Perennial, 1995.

I can also highly recommend the companion volumes called Constructing the Universe Activity Books for really getting into the mix.

An amazing collection of material and highly, highly recommended... You can check out his full website HERE.

Truncated Hexahedron (cube)

I recently made this 4-inch polyhedron out of 6 hand-cut octagons and 8 equilateral triangles. It's for a project that I hope to be able to share soon, but for now...

I love the beautiful simplicity of creating octagons from squares using simply a silver pencil, a straight edge and a compass. No actual measurements of any kind (other than getting a 4-inch square to begin with).

Typically I find myself making one or more of the five Platonic solids (although though this is not one, but a modified version of one) in various sizes and for a variety of reasons—sometimes closed like these below, but often open as well.

For example, I love the way my large-ish (approx. 3 ft dia.) open dodecahedron holds the snow...
