I think this is a great Idea. This will give 
people something fun to do. Also you know what 
would be really cool? Is if you can find 2 sites 
that have the exact same Cel from the same scene 
and make people guess which site you picked. That 
way people won't be like "I know where that Cel 
came from." Instead they would be like "Ohhh 
Brain hurting must choose right site." I think 
that would add a little fun and a nice twist to 
this hunt ^_^
