Nine-pointed star using GIMP with spyrogimp
Ever want to make a nine-pointed star using spyrogimp? Unless you're better at straight math than me, it's a little tough to figure out the numbers. Here are some that work:
A ratio of 7:1 (for example, 84 teeth on the outer wheel, and 12 on the inner) will get you a regular nonagon. For something with a nicer weave to it, try 120 outer and 48 inner. I've found that a hole ratio of about .23 works well on that last one. By varying the settings, combining different figures, applying selective shading, and removing extraneous lines, you can get some really nice figures.
