RjDj offers two objects, rj_image and rj_text, for displaying images and text on top of the main image of the scene. We briefly discuss rj_image and rj_text in their most basic form here. If you want to use them in your own scenes, however, you should also take a look at the convenience wrappers for images and text that rjlib provides (see Using rjlib).

These objects are best suited for providing basic visual feedback, but if you aren’t afraid to implement complex logic in Pd, then you can also combine them with the touch input discussed above and build simple graphical user interfaces. Bérenger Recoules has taken this technique quite far in his recent work at Stereolux. He even created an RjDj scene that’s actually a simple video game (Figure 3-8).
