New Shape

I've been working again on creating different torus shapes based on the tube structures I learned from the Beaded Molecules people.  Since they're based on 6-bead circles, which serve as hexagons, they lend themselves to circles, triangles, diamonds.  shapes with right angles come harder.  I did a post last September where I came up with several shapes.  One of them, which I did in dark brownish red, was vaguely right angled, because I used 4 9-bead circles in the middle to get the curve.  It didn't sit flat, though, and just generally wasn't satisfactory.  I was playing around the other day and came up with a much better structure.  It still uses 4 9-bead circles in the middle (they're the darker green ones) but they're arranged differently, and I like the shape much better.  As a more general thing, it's a way to make a clean right angle turn in a tube structure.
