Excerpt from the article:

Jon Sarriugarte and Kyrsten Mate are a Bay Area maker couple whose creativity knows no bounds, as evidenced by their stunning Serpent Twins 50-foot kinetic mobile sculptures on this issue’s cover. They’ve exhibited projects at Maker Faire Bay Area since 2006 along with their daughter Zolie, now 8, who has grown up with the Faire. Jon recently gave us insight into the inspiration and tech specs for the Twins.
