Polyhedra A-Plenty

Here's a 3-dimensional rendering of one of the five platonic solids - a tetrahedron.

And a drawing of one of two possible "nets" or diagrams for folding a 3-dimensional tetrahedron shape (with the addition of my light scales, of course!)













And finally, a drawing of the frame of a tetrahedron so you can see through it.




I could go on and on...




you know I can...

Next Up: Platonic Solids

Icosahedron, graphite pencils, 9x6 in., Otto
Yes, I've been playing around with the following 5 polyhedra, but as unfolded flat images, rather than solid geometrical shapes...

Why you might ask?  Well, that's just what interests me...the diagram aspect of it.  The step-by-step procedure for creating them...and of course, figuring out how to apply my light scale sequence to it.  

Which is something I've been experimenting with in each polyhedron...
