I've designed a Lego like block that forms Octahedra and Tetrahedra instead of
the conventional rectangular bricks.
I believe my blocks would be inexpensive to manufacture.
They would be a good teaching/research tool for crystallography and geometry.

If interested:

I have other pages of geometrical stuff linked to this page.

In an earlier posting, I did not capitalize the I of Index in my web address. I
apologize for any frustration that may have caused.
