Thanks for the nice comments. I afarid I have been playing a bit more
This is version 5, with a smoother strand backbone, acheived with three lines per base-pair. Essentially the N of DNA backbone strands is part of the base-pair line, with the A and opposite D on separate lines. This lets them take up intermediate positions between the main base-pair lines in the Wave. Adjusting overall line size lets the angle of twist be varied to taste.
