Tower of the Windings

Tower of the Windings, a wind-animated sculpture by James Mallos, makes its debut at World Maker Faire New York September 20 & 21, 2014. Initially conceived as a tower, this work-in-progress has evolved into an arch. The wind activated aspect is still experimental. The tensegrity structure is a tension ladder—a ladder-like arrangement of equal-length tendons pre-stressed by crossing diagonal syruts.

A new winchworm design will also debut at my "Make Your Own Windbot Muscle" exhibit at Maker Faire.This winchworm uses about 24" of a 160Q balloon as its body and about 8 grams of detergent-washed tie wire (a wire used to place concrete reinforcement) at each end of the balloon for front and back legs. There are two feet in back and one in front;
each foot is a safety loop of wire made using jeweler's round-nose pliers.

The two loops of Berkeley 1-lb test are tied using nails about 4" apart. The single loop (with knots at each end) is tied on nails about 2-1/2" apart.
