This is the code I made for my LED Ball. There's probably a couple of redundant parts - I started off with grandiose ideas and then had to hammer the routines to fit in the holes when the master plan didn't work so some bits aren't needed and I CBA to tidy the code up. There's nothing fancy in this - mostly standard routines for shift registers but i use the Output Enable to "rotate" the ball. This code does work with my Ball though and the Ball has been running continuously throughout the Christmas period.
