FizzX is a visual Box2D editor tool. Using the editor a developer no longer needs to manually hand code the creation of Box2D bodies and joints. Instead, by visually drawing it’s possible to dramatically increase productiviy allowing rapid prototyping and easy changes.

Among the available features are the ability to draw bodies, draw joints to connect bodies, automatic polygon triangulation, import images and pair them with bodies and finally a way to export the scene as a JSON structure.
