Pattern generator. Is there such a thing?

Question

css

For a long time on the net somewhere on Habré I saw the "pattern generation" service. It worked according to a simple principle, when loading an icon into a service, it generated the pattern itself. Maybe I'm confusing something, but maybe someone met a similar service?
