We’ve got computer graphics software thats so powerful it can generate images that make it seem like dinosaurs are back. But they still cant compare to the simple satisfaction you get from making a really complex hypotrochoid or epitrochoid with a marker and some perforated gears. So Nathan Friend was kind enough to build a browser-based Spirograph youre probably going to want to immediately bookmark.
The online Inspirograph, as Nathan calls it, lets you swap in gears of different sizes and choose pretty much any color your computers screen can display. And while you dont get that highly satisfying feeling of pen on paper as you make endless loops, its impossible to screw up your design on this version, unless you accidentally refresh the page.
