Vector graphics editor for designing greeting card logos using various closed shapes based on conic sections and spirographs. Written in Java and rendered using Bezier curves.
The editor supports multiple configurable objects superimposed on each other, usually with a radial symmetry, to produce intricate and interesting designs. It uses standard shapes like hyperbolas, ellipses, polygons, cardioids, centered trochoids and vaguely teardrop-like shapes; always as closed objects so they can be filled with color.
The emphasis is on being able to select and manipulate the objects with a mouse, clone the objects easily, and produce radial symmetry about a centre point. The original objects are edited using a monochrome wireframe display which can be printed at high resolution. These objects can then be filled with color using a flood-fill tool. This can be either printed or exported to PNG or SVG format, which is Inkscape-compatible. In all cases, the shapes are rendered using Bezier curves, which are used to approximate the true shape of the geometrical objects.
