I like the design direction but we will not end up with a double helix design, it is just too generic for us. However, if you could pick up a muscle theme in the image that would be great. A simplified muscle spindle might look great with your design. This could be drawn as a single helix around a spindle shape. See these sites for ideas on what this might look like: http://www.ucl.ac.uk/~sjjgsca/MuscleSpindle.gif http://www.colorado.edu/intphys/Class/IPHY3430-200/image/13-3a.jpg
