0. CONTENT CLASSES: this project contains two differently licensed classes
   of content —

   (A) Expression engine & emotion data: the source code (state machine,
       spring interpolation, spherical projection, rendering, config
       registry, etc.), the emotion configuration data (eye-ring / eye-shape
       / mouth-shape parameters, animation primitives and keyframe
       sequences) and the accompanying documentation, all independently
       written and designed;

   (B) Ball-character visual designs: the blob / wedge / gem body
       silhouettes, color schemes, ribbon and other FX visuals, and the
       overall character appearance they form together.

1. NON-COMMERCIAL USE (applies to both A and B): viewing, downloading,
