Wheeswing and carrying bag, 2014, canvas, steel, plastic, webbing, nylon. I designed and produced a small run of take-anywhere, adventure swings. With its rock-pockets for weighting the throw line, and no-knot wrapping attachment system, it is easy to put up and easy to take down. Huge Thanks to Tae Kim of Alite for sewing and design advice.  Wheeswing photos by Jan Sturmann

Grittiegrip, 2015, webbing, shock cord, velcro. I designed and produced this fort building toy prototype to be just the right length and spring for connecting branches, furring strips, or furniture.
