A browser-based tool for designing geometric kidney-like forms, built from overlapping circles connected by tangent-smooth Bézier curves.
Shapes are constructed from three or more circles. Each pair of adjacent circles is bridged by a cubic Bézier curve whose endpoints are tangent to the respective circles, producing a smooth, flowing outer contour.
- Drag circle centers to reposition
- Drag the edge handle to resize
- Use the Flow slider to tune how much the connectors curve
- Export as a clean SVG stroke — ready for Illustrator or a pen plotter
