This photo sequence will show you some of my first experiences with Wild Gears. It’s Spirograph on steroids! Click on any picture to enlarge.
Note that I’m using tiny bits of Spiro Putty, or poster putty” (affiliate link goes to an example on Amazon, but it’s also available in office and art supply stores) to hold things down. Aaron in his videos uses weights. Whatever works.
Aaron Bleackley’s Wild Gears Kickstarter campaign includes a video, and will give you a good overview of the project.
