Variations on light fixture 15.

Variation "A".  No soft edges; all sharp angles.

Variation "B".  All soft edges, inward shape.

Variation "C".  Blend of soft curve with sharp angles, outward shape.

Variation "D".  Same as "C", except inward shape.

Variation "E".  Similar to "C" but with a bump back to the interior in the middle.

I had two others besides these, and I might do more, but so far, I am liking "A" and "B", and the converse design of "B" which would be simply the same design except the curve is to the outside. I like these as a series, and might make them my first official series...sad naming convention, but I think I'll just stick with "Light Fixture 15".
