HOBERMAN - Transformable design
Milwaukee, Wisconsin
Beginning as a tight cluster, the Expanding Helicoid smoothly expands to fill the spiral staircase at the center of Discovery World's permanent biotech exhibit. Visitors have the remarkable sensation of being inside the sculpture: As it contracts, it seems to disappear into the stairwell; as it expands, it seems to grow like a living plant. Bound by two spirals, like the DNA double helix it resembles, the helicoid itself is like a living organism, evolving as it expands.

The Expanding Helicoid was awarded a Silver IDEA 2008 Award for excellence in the Environments category by the Industrial Designer's Society of America and BusinessWeek.
