Mathematical based floral ornaments, derived from the polar coordinates equation r=b+sin(aθ), which is a slight generalization of the Limaçon and Rose curves.

Top left: curve with a=5 and b=1.25, non-self-intersecting
Top right: curve with a=(5/2) and b=1.08, single-level self-intersecting
Bottom left: curve with a=(5/3) and b=1.08, two-level self-intersecting
Bottom right: curve with a=(5/4) and b=1.08, three-level self-intersectingThe self-intersecting curves are displayed with "even-odd" fill algorithm.

For other patterns made with the quasi-Limaçon/Rose equation r=b+sin(aθ), see File:Interlaced-Triangles Brunnian-link alternate.svg and File:Quinquetra-interlaced-alternate.svg.
