*В Perhaps this value has another name, but I'm no mathematician please let me know if there's a more simple name. For gears which have a prime number of teeth, they result in designs with a number of points equal to the number of teeth in the ring. As you might expect, for rings with a prime number of teeth, the number of points is always that number.

Pick a random drawing, or set the parameters manually, and let's draw it with HTML spirograph.

Excel has a function for least common multiple, and thus it's easy to write a formula this purpose: =LCM(B$1,$A2)/$A2 where B1 contains the number of teeth in the outer ring and A2 contains the number of teeth on the gear see the screenshot.Or just download the Excel file below. HTML Spirograph is a digital remake of the originally mechanic device which creates amazing drawings with unlimited variations. I found that, for a given ring and gear size, the number of 'points' can be determined by taking the least common multiple (LCM) of the number of teeth on each of the two elements (ring and gear), and dividing it by the number of teeth on the gear.* Using this equation you can make a spreadsheet with columns as ring sizes and rows as gear sizes to help you choose the numbers of teeth for the elements of your toy.

When setting out to design a spirograph, I first fiddled around with a few different size rings and gears. I have tested it on my PC and it works fine, you can zoom in and out using your mouseвЂ™s track wheel.

The number of teeth on the outer ring and the inner gear determine the number of 'points' on the resulting full drawing.
