Similar to the Dome Diffuser, the Bounce Card for the A1 on-camera flash allows you to bounce the flash and also direct some light on to the subject as fill. That will create a soft light with a more directional feeling.
The Bounce Card comes with a handy magnetic mount, and it's stackable so it can be used in combination with other A1 Light Shaping Tools like gels, for example. All of which allow you to be more creative with light.
