S.U.M. Thoughts

Ever want to take your spirographs to the next level? Yeah, I know that’s not really something at the top of your to-do list, but the Guilloché Pattern Generator is a cool way to generate the math-based patterns that are common elements in paper money. Named guilloché after the French engineer Guillot, who invented a machine that could scratch fine patterns and designs on metallic surfaces, the patterns are generated with a series of variables controlled by sliders. So now if you ever want to secede from the Union, we just made it easier for you to design your new currency. You’re welcome.
