+ * An animation playfield containing two "java drinkers", that
+ * both bounce off the sides of the playfield.<p>
+ *
+ * One of the java drinkers moves slow and spins fast, while
+ * the other java drinker moves fast and spins slow.  When
+ * the two java drinkers collide, they both play a bump
+ * sequence - at different speeds.<p>
