bruzie: With apologies to the last finder, who would have found this puzzle impossible to solve as technological changes (for the worse) have prevented me from presenting this puzzle in the way I had originally intended, and instead of trying to do yet another work around, I'm archiving this puzzle to try and come up with a new idea.
I'll leave the container where it is for those of you who have solved (a while back), but not yet picked up.
Thank you to those who managed to see in the same way as those who can't.
