"Well, we're in a pickle. There are 9 of us in the special cell block, arranged in a circular fashion and facing outward so that we can't see each other. And worse, they don't want us 'to get too comfortable' so we are reassigned to different cells randomly each day after the morning walk."
"You're right, Mr. Fredege. I eavesdropped the another group talking about toilets but we don't have the comfort of having them in our own cells, so that's out. The lights in my cell have been acting weird lately, but I don't know what that's about..."
"It think I might, Phiddler. I overheard the guards talking, and it seems there is an issue with the wiring...rats or something of the sort, and now when one of us switches on or off the lights in our cell, the lights of the adjacent cells are also switched."
"Hmm...good observation K-croc. I think we may be able to use that, but we'll have to be careful. We need to avoid messing with the lights when the guards are walking by our cells, which as far as I can tell is at random intervals, so whatever we do has to be independent of time intervals."
"Alright, where do we start?"
