We’ve featured the work of Jack Spiggle, aka NanoRobotGeek, a couple of times in past issues. And we’re very proud to be able to say that he’ll be writing a How I Made for our next issue, unveiling some of the thought processes behind this free-form, solar-powered kinetic sculpture. Like a lot of his work, this uses solar power stored in capacitors, which triggers an action when a certain amount of charge is reached. And like all of his work, it’s absolutely beautiful.
