Originally thought up by Ben Hartland and came in to play during college where class mates would alter the appearance of the Cyber Wookie.
The rules of Cyber Wookie are:
1. Do not undo anything someone has done without popular demand.
2. Do not cover up someone elses modification, but you may add to it.
3. It must be a Wookie.
