Useful Resources for Puzzle Solving
Given the variety of topics covered by the MIT Mystery Hunt, I figured it would be a good idea to have a set of tools available for whatever comes up in this and other puzzle hunts. So this thread is for posting and puzzle-solving primers, tools or other resources that you may have come across this year or elsewhere.
One useful for the Mystery Hunt itself: http://devjoe.appspot.com/huntindex/
A list of all the puzzles from the 2000-2011 hunts, along with what topics they covered. Nice to see the variety of topics that have been used over the years, along with how they may have been used.
