Two small stepper motors drive two copper helixes.  The spiral appendages face each other 
to engage in a mysterious electromechanical dance.

The precision motors are electronically synchronized so that their copper spirals rotate together in unison.  
Occasionally the spirals softly touch.  Whenever the two helixes touch the motors reverse direction,
and the dance goes on.

Double Helix has been exhibited at:
Parque de las Ciencias, Granada, Spain.
   phaeno Museum, Wolfsburg, Germany.
Science Museum of Minnesota, St. Paul, MN.
Inventure Place, Akron, OH.
   1994   The Exploratorium, San Francisco, CA.
