Look Twisted Mystery Cache

This cache is inspired by an excellent series of puzzles by Footsore and Weary that has also been expanded by Parmstro, Tjapukai, Ian Too and the Purple Pineapples......It will eventually form part of a puzzle circuit collectively created by Coldrum, Dondesole and myself.
