Chilik is similar in concept to Nullsoft’s excellent AVS plugin for Winamp, extended to 3D. It presents a tree-view of a scene graph, where the user can insert or move different models, special effects (such as particle systems), or scene modifiers (blurs, clones).
The screen saver aspects of the program include saving/loading individual scene trees, an interactive preview of the rendered scene as it is edited, and sequencing options (such as which scenes to use and the transition mode between them).
