I've made probably hundreds of spirograms, using the Inkscape Spirograph Effect feature. Many of them I've used as a starting place for abstract artwork (and will continue to). But there are many, many more, for which I don't see any other future other than their own amazing beauty.
So I've used color to enhance their own innate beauty, and compiled them into what I'm calling samplers. (In the sewing or needlecraft world, a sampler is a piece of fabric on which one sews all different kinds of stitches, usually to display one's talent. In this case, there's not much talent, just manipulating the dialog to configure different spirograms.) I hope to discover more unique spirograms, but for now, these are the best.
One more quick note. In the middle of these images, I've grouped spirograms, which initially appear to be solid black. But after reducing their stroke width, incredibly intricate patterns are revealed. Around the outer parts of these images are spirograms which have the standard stroke width=1, and need no further editing. I reallly like the fine, delicate look of the ones with reduced stroke width.
