Duvall, an innovator in fabric structure design-build ideas for 15 years, has introduced a new concept in booth design at this year's Exhibitor show in Las Vegas, March 9-13, 2008.

Duvall's booth structure intersects two large, lightweight elliptical trusses, defining a distinctive space within a 20' x 30' booth space; the structure sits diagonally within the rectangle. One leg of the truss is transformed into a curvy squiggle which seems to defy gravity as it gives definition to the entry.

The ellipses rise to 12' 6" high, and touch the ground with only four points. Each point is a very acute and complex machined hub formed by three intersecting legs of the truss.

According to designer Charles Duvall, "The concept is to define an exhibit space with the very lightest materials and simplest structure imaginable, yet introducing one curvilinear, animated deformation which seems magical, organic, and transformative. The transformation breathes precious life into an otherwise minimalistic engineered truss."

The overall structure weighs only 150 pounds and is comprised of thin-walled aluminum tubing precisely bent to form each ellipse. Fabric encloses the triangular truss system in an envelope so that no frame is exposed.

Because the footprint of the booth is so small, the balance of the sub-divided space is available for circulation, demonstrations and conversations.
